Kingston’s unique location provides an interesting diversity to field trips throughout the region.
New Insights into the Tectonic and Metamorphic Architecture of the Composite Arc Belt and the Frontenac-Adirondack Belt near Perth, Ontario, Grenville Orogen – Michael Easton (Ontario Geological Survey).
This is a Pre-conference field trip, Duration: 1 day (May 14): Note: Trip starts in Kingston the morning of May 14 (Sunday) and ends in Kingston the evening of May 14. Located adjacent to Highway 7, the Maberly shear zone is one most accessible structural features in the Grenville Orogen. It is also one of the oldest (circa 1162 Ma) and represents the boundary between the Composite Arc and the Frontenac-Adirondack belts. This one-day trip highlights the results of recent detailed studies by the Ontario Geological Survey. The fieldtrip will examine key outcrop exposures providing evidence of the tectonic, magmatic and metamorphic history of this boundary. Field trip discussions will focus on the evidence for higher metamorphic pressures than previously thought, the character of the pre-Frontenac intrusive suite (circa 1178-1160 Ma), and the relationship between metasomatic mica-apatite-pyroxenite rocks of the Frontenac-Adirondack Belt and their tectonic equivalents in the CMB boundary zone. The trip compliments both the session on the Metamorphic Architecture of Orogenic Belts and the post-meeting trip on the Tectonic and Metamorphic Architecture of the northeastern Composite Arc Belt and the Central Metasedimentary Belt boundary tectonic zone. The trip will begin and end in Kingston, Ontario. This field trip is sponsored by the Canadian Tectonics Group.
Max 30 participants. 8 am to 6:30 pm, 14th May–1 day. $169.5
Tectonic and Metamorphic Architecture of the northeastern Composite Arc Belt and the Central Metasedimentary Belt boundary tectonic zone, Grenville Orogen – Manuel Duguet (Ontario Geological Survey (OGS)) and Michael Easton (OGS).
What better way to follow through on the discussions from the theme session on the Metamorphic Architecture of Orogenic Belts than to examine a major tectonic boundary in the Grenville Orogen less than two hours drive from Kingston. This field trip will highlight recent results that indicate a more complex magmatic and metamorphic history than previously recognized. The fieldtrip will examine key outcrops exposures providing evidence of the tectonic, magmatic and metamorphic history of this key area in terms of understanding the linkage between the gneisses of the Laurentian Margin (infrastructure) to the northwest and the Composite Arc Belt. The trip will foster field discussions on complex thrusting history, the recognition of circa 1150 Ma metamorphism and magmatism in parts of the area, and the history of syenite magmatism, metasomatism, and rare element mineralization between 1080 and 1030 Ma. This trip lasts for 4 days and starts in Kingston on the morning of May 18 (Thursday) and ends in Kingston the evening of May 21 (Sunday) and is sponsored by the Canadian Tectonics Group.
Max 25 participants. 8 am to 6:30 pm 18th May–4 days. $734.5
Sedimentology, stratigraphy and diagenesis of the Potsdam Group in the Kingston region – David Lowe and Robert Arnott
This 1 day trip will focus on sections of the Cambrian to Early Ordovician Potsdam Group, a composite siliciclastic unit unconformably overlying ~1 billion year old rocks of the Grenville Province and, in this area, sharply but conformably overlain by the Theresa Formation – the basal unit of the carbonate-dominated Beekmantown Group. During this trip will travel to parts of Ontario northeast of Kingston then south across the St. Laurence River to visit sections of the Potsdam Group. We will examine aspects of the Potsdam’s sedimentology, stratigraphy and diagenesis in the southwest part of the Ottawa Embayment, a fault-bounded basin with Lower Paleozoic fill that is part a much larger feature – the Ottawa graben. Starts at 7:00 am Saturday, May 13. Meet in front of Douglas Library on University Ave near the intersection of University Ave and Union Street (Queens Campus). Return to same location at 6:30 pm. Please note that this trip involves travel to the USA, and participants are responsible for ensuring they have necessary documents for crossing the border.
Max 25 participants. 8 am to 6:30 pm, 13th May–1 day. $90.
Drumlin morphology and origin related to erosion below fast flowing ice of the Laurentide Ice Sheet in Southern Ontario and Upper New York State – Trip leaders: Nick Eyles, Shane Sookhan and Lina Arbelaez-Moreno (U of Toronto), Martin Ross (U of Waterloo), Niko Putkinen (Geological Survey of Finland).
New modelling of the Laurentide Ice Sheet reveals the presence of more than 100 fast flowing ice streams. This three day field trip will travel through the superbly exposed glacially-streamlined ‘hard’ and ‘soft’ beds of the former Ontario Ice Stream in Southern Ontario and Upper New York State. We will examine rock drumlins and megagrooved limestone surfaces of the ‘hard bed’ seen immediately south of the border of the Canadian Shield and the downglacier change to classic ‘drift’ drumlins composed of sediment, of the ice stream’s ‘soft bed.’ We will review variation in drumlin morphology using new imagery such as LiDAR, together with their stratigraphy where exposed along the Lake Ontario shoreline. The trip will begin at 8.30 am on the 13th in Kingston and end in at 6 pm on the 14th in Kingston, Ontario.
Max 25 participants. 8:30 am, May 13-14–2 days. $339.
Accreted terranes of the Newfoundland Appalachians – Cees van Staal & Alex Zagorveski
The Newfoundland Appalachians trans-island field trip will take participants to some of the best preserved ophiolites, melanges and island arc terranes in the Appalachian mountain belt. Crossing several suture zones, including the main Iapetus suture, participants will explore the tectono-stratigraphy of the various oceanic and micro-continental terranes and their tectonic complex tectonic interactions during successive accretion to a progressively expanding composite Laurentia from the Early Ordovician to Devonian. The five day trip will take you from Stephenville to Gander showing spectacular geology framed by the beauty and ruggedness of Newfoundland. This field trip is sponsored by the Canadian Tectonics Group .
May 19-24–5 days. $1243.
Shallow Neritic Marine Carbonates on a Tropical Ordovician Earth –Guy Narbonne (Queen’s) and Noel James (Queen’s).
Shallow water marine carbonate rocks are beautifully exposed in the Kingston area and many buildings are made of these rocks such that the town has the nickname ‘the limestone city’. The easily accessible outcrops have been little altered since they were deposited ~ 450 million years ago and the components are easily visible making aspects of sedimentology, paleoecology, and diagenesis easily understandable to everyone. The day-long field excursion will visit sections that range from peritidal through ooid shoal to reefal and subphotic paleoenvironments. Paleoceanography will range from arid tidal flats, through the paleothermocline into interpreted cool water outer ramp storm and slope deposits. This trip is designed for participants who are neophytes, those who want to know more about carbonate rocks or those who are fascinated by this period in deep time.
Max 25 participants. 7 am to 5:00 pm, 14th May–1 day. $113.
Bedrock to Beaches: Local geology of the Kingston area – Dugald Carmichael & Herb Helmstaedt
The 1-day Bedrock to Beaches field trip will take participants from Kingston to Prince Edward County and back. Along the way, we shall examine and contemplate metasediments that were heated, squeezed, and intruded by granite ~1170 million years ago, sandstone deposited by rivers and wind ~490 million years ago, limestone and shale deposited in tropical seawater ~455 million years ago, faults that displaced the limestone perhaps 176 million years ago, drumlins shaped by a continental ice-sheet ~20,000 years ago, a shoreline created by a giant proglacial lake ~13,200 years ago, and a thin soil full of frost-heaved limestone nodules that nowadays nourishes many of the best vineyards in “the County”.
8 am to 5:00 pm, 14th May–1 day. $113.
Regional glacial geology and groundwater, eastern Ontario – Hazen Russell, Andy Bajc, David Sharpe
The trip traverses the Canadian Shield and Paleozoic geology of the eastern Lake Ontario Basin to highlight its contrasting style of erosion and sedimentation. The tour reviews field evidence of the influence of bedrock lithology and structural control on micro / macro scales of erosional and depositional regimes. Sedimentary deposits, landforms and landscape architecture are integrated into regional conceptual models relevant to groundwater supply and management in the transition from thin to thick sediment setting of eastern Ontario.
9 am to 5:00 pm, 13th May–1 day. $113.
