FT PRE 1. 
Depositional controls and sedimentology of the Lower Cretaceous McMurray Formation

Integration of outcrops, modern environments, geochemistry, geomicrobiology, petrophysics, seismic, and production data

Outstanding 60-80 m high exposures of the Lower Cretaceous McMurray Formation, drill hole data from behind outcrops and regional subsurface mapping provide a strong basis for understanding depositional controls and sedimentological aspects of this fluvial to marine transgressive succession and the discussion. Discussion topics include: Bedrock control on fluvial and tidal sedimentation; local to continental scale paleo-drainage systems and sediment provenance; stratigraphy in low-accommodation settings; implications of the backwater effect within the fluvial-marine transition. Architectural elements of the fluvial-marine transition including: open estuaries; small-scale stacked channel deposits; tidal-flat deposits and large-scale tidal-fluvial point bar successions. Process sedimentological analysis of tidal-fluvial point bars including: Types and genesis of mudstone-clast breccias; quantitative geometric understanding of inclined heterolithic stratification (IHS) and the processes, which form it (i.e., seasonality, metre-scale cycles etc.); chute channel deposits and geometric expression; evidence for debris flows; controls on mud deposition and preservation in the fluvial-marine transition.

FT PRE 2.  Sedimentology and Paleontology of the oldest Ediacaran communities of Newfoundland


The Mistaken Point Ecological Reserve and UNESCO World Heritage Site offers a unique perspective on the geobiology of the late Ediacaran period, including deposits related to the Gaskiers glaciation (potentially the last of the ‘Snowball Earth events’), and the first radiation of complex, macroscopic eukaryotes - the ‘Ediacara Biota’. The exposures around Mistaken Point preserve a spectacular deep-water turbiditic succession that record 15 million years of deep water sedimentation off margin of the Avalon microcontinent. Attendees will be able to examine the fascinating interplay between sedimentation, surface colonization by microbial mats, volcanic ash fall, and the unique circumstances that led to the preservation of Ediacaran fossils. These fossils are dominantly “Rangeomorphs” - an extinct lineage of organisms whose “fractal” modular construction has defied classification – and which represent the pivotal moment in Earth History when ‘Life got Big’.


The field trip will include visits to the extensive “Gaskiers” glacial deposits and overlying cap carbonate sediments, followed by two days hiking through the Ecological Reserve and surrounding sites along the historical “Irish Loop” of Eastern Newfoundland. Detailed stops will include several world-class, research intensive fossil sites, and the sedimentological context within which these organisms evolved, thrived, and ultimately went extinct prior to the Cambrian explosion.

FT MID 1. The Upper Ordovician Taconic foreland succession near Quebec City

Transition between the Precambrian gneisses, Ordovician carbonate and clastic foreland units, Montmorency falls (Photo: D. Lavoie). 

Stop 1: Transition Black River - Trenton, Rivière Ste-Anne à St. Alban
This stop offers the best exposure of the unconformable contact between the Black River and Trenton groups in Quebec. The contact marks an important faunal turnover between the warm-water assemblage of corals, stromatoporoids and green algae in the muddy limestones of the Black River Group to cool-water like assemblage of crinoids, brachiopods, bryozoans and red algae of the coarse-grained limestones of the Trenton Group. A significant increase in phosphate content is recorded in the Trenton Group sediments above the unconformity
Stop 2: Utica Shale; Cap Santé - St. Lawrence Shore
This stop displays one of the best exposure of the limy black shales and fine-grained limestones of the Utica Shale. The unit with a strong condensate smell, is rich in graptolites and cephalopods and was, from 2006 to 2010, the target for potential shale gas development.
Stop 3: Transition from the Precambrian gneiss to Trenton carbonates to Utica Shale and Lorraine flysch; Montmorency Falls
At this stop we will see the onlapping Upper Ordovician basal sandstone and Trenton Group limestones over the Precambrian basement. This locality offers the only known bioconstruction (mud mound) in the Trenton Group in Québec. The Montmorency Fall is the morphological expression of a major fault that regionally marks the contact between the Precambrian and the Lower Paleozoic platform. On the downthrown block, the top of the Utica Shale is conformably overlain by grey mudstone and siltstone flysch of the Lorraine Group derived from erosion of the Appalachians thrust sheets that were encroaching along the continental margin at that time.   

Field trip leader(s): Denis Lavoie (Geological Survey of Canada, Canada)
Number of participants (Min/Max): 40 to 80
Departure/Return: Québec City Convention Centre, 8:00 am to 17:00 pm
Duration: 1 day
Date: August 15th, 2018
Cost: $ 100 

FT MID 2. Visit of the INRS’ large-scale laboratories

The large-scale flume making waves.

The laboratories for scientific and technological innovation in environment (LISTE) are located in the Metropolitan Québec Technology Park, because they are too large to be hosted within conventional laboratories. Three facilities will be visited:
The Environmental hydraulics Laboratory, is one of the largest in the world: 120 m long, 5 m wide, and 5 m deep. It has a wave maker, can reproduce tides and generate currents, to perform simulations at scale from 1:5 to 1:1 for application such as modelling the stability profile of beaches, modelling sedimentation in ports and marinas, studying the interaction between waves and currents on coastal and offshore structures.
The CT-Scan lab is equipped with a medical CT-Scanner and a wide range of instruments with a special focus on the study of sediments. It is the only laboratory in the world allowing the in-vivo study of sedimentary dynamics with a hydraulic mini-flumes that reproduces one-way currents, waves, and gravity currents, and that can be inserted within the CT-scanner. Hence, it enables the study of turbulence (by PIV), bathymetry, and suspended sediment concentrations (by CT scan) simultaneously and without perturbation of the dynamic system. Sediment cores are analysed routinely.
• The Environmental Biotechnology Laboratory is a technological platform that enables the development and scaling up of industrial bioprocesses from residual materials or synthetic media. The industrial bioproducts can be enzymes, bioplastics, biopesticides, biofuels, solvents, surfactants, biocleansing, agents, platform molecules, and many others. The facility includes two instrumented fermentation laboratories, one reserved for waste and the other for synthetic media in order to avoid any contamination. Each fermentation laboratory has its own bioreactors (of 5-, 15-, 150-, and 2000-litre capacity).

FT MID 3. Archaeology, Landscape and Quebec City History

Photo credits to come...

Come join two archaeologists from Laval University to lead you through a 2 km walking tour of Old Quebec where they will share with you their knowledge of the city where they work as archaeologists. The group will meet at the Dufferin Terrace overlooking the port of entry to North America where salt and fresh water meet. After a brief description of the local landscape, the presence of First Nations and the founding of Quebec in 1608, the group walk through the oldest park in North America and then we will head up to the Citadel to discuss the fortified city. Next, we head to Morrin College a historic prison which later served as an English language college. We will then descend to Lower Town to see the Intendant’s Palace where New France’s Intendant administered justice and looked after the economic development of the colony. While in Lower Town we will walk along St. Paul Street known for its restaurants and antiquarian shops. The tour ends at Place Royale the heart of North America French culture with its picturesque 18th-century reconstructions. While the tour ends in Place Royale, participants are invited to join the archaeologists for refreshments at the Auberge Saint-Antoine, a local hotel renowned for the hundreds of artifacts on display, artifacts excavated by your hosts!

FT MID 4. Québec, a Fortified City: Geological and Historical Heritage

Quebec City is located at the junction of three geological provinces, bestowing upon it a unique geological panorama, which includes a historical district that dates back to the first days of the colony. Since 2004, Natural Resources Canada has been organizing, in collaboration with Parks Canada, a multidisciplinary urban tour through the streets of Old Quebec, combining geology and history. Quebec City’s geological history goes back more than a billion years and can be explained by plate tectonics. According to this theory, the Earth’s crust is divided into plates that slowly move against one another. At each of the selected stops, field trip participants will discover clues to a long-disappeared ocean, the movement of massive rock masses over long distances, up to the very threshold of the city, and the passage of immense glaciers that covered the region for thousands of years. We live on a dynamic planet and various elements remind us of this on a periodic basis. We will also see how earthquakes and scree are the results of the region’s geological heritage. Quebec, a UNESCO World Heritage Site, is the only city in North America to have retained major parts of its original defence system. The Fortifications of Quebec are a 4.6-km-long defence system that encircle the Upper Town promontory. Like nowhere else in North America, the old city’s defence system follows a classic urban style, characterized by flanking, defence in depth, adaptation to the city’s topography and urban layout. More than just the vestiges of the military art of war, the Fortifications of Quebec also bear witness to the era of fortified cities between the 17th and 19th centuries. Everywhere within Old Quebec’s walls, you can feel the military presence that dominated the city and is a reminder that the city’s past was punctuated by the beat of the war drum.

The Middle and Late Quaternary succession of the north shore of the Middle St. Lawrence Estuary is perhaps the most contrasting record of eastern Canada due to several combined factors: steeply sloping terrain bordering the faulted southern edge of the Canadian Shield, deep glaciated troughs in major valleys, glacial lakes impounded by advancing and retreating lobes and outlet glaciers of the Laurentide Ice Sheet, rapid local glacial isostatic adjustments and repeated global eustatic marine incursions.  This excursion will bring participants to the best available sections in the Mont St-Anne area and vicinity:
- Outcrops on the banks of Rivière Jean-Larose: these sections, which lie in the St. Lawrence Lowlands near the faulted southern edge of the Shield, expose (1) a complex succession of pre-LGM  fluvial gravels, glaciolacustrine rhythmites and deltaic sands, overlain by (2) coarse outwash gravel and till, which are in turn overlain by (3) fossiliferous marine muds and deltaic sands.
- Outcrops in the Saint-Tite-des-Caps basin: this section exposes peat beds, recording a boreal environment, and glaciolacustrine rhythmites, recording at least two episodes of ice-marginal impoundment, can be observed under the regional matrix-dominated surface till (LGM). 
- The Sainte-Anne-du-Nord deltaic complex: glaciofluvial ice-marginal sediments and ensuing forced regression deltaic sediments are exposed in a series of gravel pits that almost reach marine limit.
- if time allows, deposits associated to the deglaciation and/or foreshore.

FT POST 1. The Stratigraphic Record of the End-Ordovician Mass Extinction on a Storm-Dominated Carbonate Ramp, Anticosti Island, Eastern Canada

Chute Vauréal (Photo: ©René Bourque)

Carbonate sedimentary rocks like those superbly exposed on Anticosti Island in the Gulf of St-Lawrence are, if correctly ordered and interpreted, an inventory of considerable information for helping decipher the cause-and-effect relationships within the ocean-atmosphere-biosphere system in the deep geological time. The Upper Ordovician to lower Silurian Anticosti succession consists of approximately 900 m of undeformed fossil-rich limestone and minor siliciclastic rocks that were deposited on a storm-dominated tropical carbonate ramp. Thick, lithologically repetitive successions like those in Anticosti Island, however, present a challenge to a stratigrapher attempting high-resolution correlation of such units even at a regional scale. By integrating sequence sedimentology with species-based biostratigraphic packages and chemostratigraphic profiles, we are now able to produce high-resolution stratigraphic models and to provide insight into the End-Ordovician mass extinction.

This trip will focus on world-class exposures of the Upper Cretaceous succession in the Henry Mountains Syncline of southern Utah adjacent to the world-renowned Capitol Reef National Park and other scenic attractions. The stratigraphy comprises the Dakota Formation, Mancos Shale (Tununk Shale, Ferron Sandstone, Blue Gate Shale), Muley Canyon Sandstone, Masuk Formation, and Tarantula Mesa Sandstone, and collectively is equivalent to the well-known succession of the Book Cliffs, 100 km to the north. The succession is spectacularly exposed in three dimensions at scales ranging up to that of entire depositional systems, allowing investigation of stratal stacking patterns at all levels. The trip will focus primarily on the Turonian Ferron Sandstone, which has been extensively investigated by both trip leaders and their students over the past 12 years (leading to numerous publications in the international, peer-reviewed research literature). Among the geological features exposed in the Ferron Sandstone are incised valley fills, distributary channel deposits, and growth faulted delta front deposits. Stratal stacking patterns are exposed in both depositional dip-parallel and strike-parallel transects, and have been interpreted to record sediment accumulation under strong forcing from falling sea-level.

The field trip will provide an overview of the Paleozoic and Mesozoic basins of the Maritimes of Atlantic Canada. We will begin in the Cumberland Basin examining fluvial sediments of the Cumberland Basin, a salt withdrawal basin where rates of accommodation were so rapid that trees of the Carboniferous forest were preserved upright. Syndepositional collapse structures, channel bodies and coal deposits of the Carboniferous section will be viewed along the cliffs of the Joggins UNESCO World Heritage site.
The trip will then continue to examine the rift succession of the Mesozoic Fundy Basin. We will study the Triassic succession of fluvial sediments, followed by aeolian strata with 5m dune sets, with deposits of playa lakes above. The succession ends with the flood basalts of the failed Fundy rift at the beginning of the Jurassic.
This field trip will be held in conjunction with the Conjugate Margins Conference Halifax 2018

FT POST 4. The Lower Paleozoic Rocks of the Gaspé Peninsula

Massive algal-stromatoporoid-bacterial reef front, Upper Silurian, Gaspé Peninsula, Québec (Photo: D. Lavoie).

The Paleozoic succession in eastern Quebec consists of Cambrian-Upper Ordovician deep marine passive margin to foreland continental slope deposits. After the Middle-Late Ordovician Taconian Orogeny, sedimentation during the Early Silurian to Early Devonian was dominated by clastic deposits with however, two major shallow marine carbonate successions rich in cryptomicrobial and metazoan fauna and local reefs.
The excursion will allow observing the various types of faunal-rich, platform-derived limestone conglomerates that are used to correlate the thick fine-grained dominated Cambrian-Upper Ordovician deep-water succession. The Silurian carbonate facies will be a highlight of the trip with exquisite examples of diverse cryptomicrobial constructions as well as deep stromatactis-rich mud mounds and fringing reefs. The field trip will be concluded with a visit at the Museum of Miguasha Park, a world heritage UNESCO site with its spectacular collection of Late Devonian fishes.

FT POST 5. Landforms, sedimentary facies and stratigraphic architecture of a deglacial, forced-regressive context: the Québec North Shore

Exposures of glacio-isostatically uplifted Late-Quaternary proglacial and paraglacial deltaic and coastal deposits at the mouth of the Portneuf River, Québec North Shore (Photo: P. Lajeunesse)

The landscape and Quaternary geology of the Québec North-Shore, i.e., the north shore of the Estuary and Gulf of St. Lawrence, are characterized by the occurrence of a series of thick and extensive deltaic complexes composed of gravel, sand and mud. These deltaic systems were initiated during the retreat of the Laurentide Ice Sheet from the region between 12000 and 10 500 years ago in a context of falling relative sea level.
This trip will allow the observation of glacio-isostatically uplifted successions of subglacial, glaciomarine, deltaic and paraglacial sediments that are well-exposed along the modern shoreline between Tadoussac (mouth of the Saguenay Fjord) and the town of Franquelin. Terrestrial glacial, glaciofluvial and glaciolacustrine landsystems associated with phases of stabilization and/or readvances of the Laurentide Ice Sheet margin during the Younger Dryas will also be visited inland. 

Field trip leader(s): Patrick Lajeunesse (Université Laval, Canada), Jean-François Ghienne (CNRS & Université de Strasbourg, France), Pierre Dietrich (University of Johannesburg, South Africa), Antoine Morissette (Université du Québec à Rimouski, Canada)
Number of participants (Min/Max): 10 to 20

FT POST 6. Chemical and Biochemical Deposition on a Paleoproterozoic Shelf: The Gunflint Formation and Overlying Ejecta of the Sudbury Impact Layer

1.85 billion-year-old Sudbury ejecta horizon (left) and contemporaneous stromatolite and iron carbonate grainstone from the Gunflint Formation (right)(Photos: P. Pufahl)

The 1878±1 Ma Gunflint Formation became famous in 1954 when Tyler and Barghoorn published an article in Science on the occurrence of fossil bacteria in dense black chert near the base of the formation. This was the first definitive proof of life in the Precambrian, and generated a rush to explore for microfossils in similar Proterozoic environments. Pictures of the famous Gunflint microbiota are in most historical geology text books. The presence of large iron ore deposits in correlative sedimentary rocks in the United States, and access to an extensive drill-core inventory, has led to a profound understanding of the sedimentology and stratigraphy of these iron formations and siliciclastic sediments. In addition, studies of both lateral and vertical geochemical variations in shore to shelf-break transects has yielded a wealth of information about the paleoceanography of this Precambrian shelf. Consequently, the Gunflint Formation and related units to the south are probably the best understood succession of Proterozoic chemical and siliciclastic sedimentary rocks in the world. After iron formation deposition ended, at ~1850 Ma, a 10-km-wide meteorite impacted near what is now Sudbury, Ontario, creating the second largest known impact structure on Earth. The ejecta from this impact blankets the top of the Gunflint Formation and separates it from the carbonaceous shales of the overlying Rove Formation. Numerous outcrops in and around Thunder Bay, Ontario highlight the ejecta layer’s sedimentologic features, providing a robust record of the depositional processes that accompany a high-velocity impact. In many ways, this record is better than that of the K-T boundary event. This fieldtrip is designed to explore the sedimentology and microbiology of iron formation through an appreciation of the biotic and abiotic precipitation processes that led to its accumulation. These processes will be interpreted in a sequence stratigraphic context to provide a framework for understanding the complex paragenesis of iron formation lithofacies. The presence of the Sudbury ejecta horizon offers a unique opportunity to investigate base-surge and tsunami deposits that punctuated iron formation deposition.
