Please make your reservations as early as possible to avoid disappointment!

1. Geology of the Mesoproterozoic Sibley Group (May 8-9) (Phil Fralick, Lakehead University and Mark Smyk, Ontario Geological Survey) This trip will examine the depositional architecture of a playa-alluvial succession developed in an intracratonic basin. This pristine sequence records the effects of both climate and tectonics on sediment character.

3. Geoarchaeology and Deglaciation History of the Thunder Bay area (May 9) (Brian Phillips and Joe Stewart, Lakehead University) Soon after deglaciation, native peoples established habitation sites. This trip will examine how the local geomorphology controlled the location of these sites and the nature of human activities.

Post-Meeting:

4. Geology of the Paleoproterozoic Gunflint Formation (May 12) (Phil Fralick, Lakehead University) The Gunflint Formation records a chemically dominated shelf sequence in which silica- and iron-rich precipitates predominate. This trip will examine the role that both physical and chemical processes played in various shelf environments.
5. Glacial History and Regional Till Sampling in the Archean Shebandowan Greenstone Belt (May 12)

(Andy Bajc, Ontario Geological Survey) The Shebandowan greenstone belt, host to a variety of precious and base metal deposits, is a bedrock-dominated terrain, typically having thin till cover. Till sampling techniques and resultant gold grain and other heavy mineral results will be examined in an exploration context.

6. Geology of the Archean Steep Rock Lake - Finlayson Lake Greenstone Belt (May 12-13) (Denver Stone, Ontario Geological Survey, Kirsty Tomlinson, Geological Survey of Canada and Ray Bernatchez, Atikokan Resources Inc.) This 3.0 Ga assemblage consists of ultramafic to felsic metavolcanic rocks and chemical-clastic sedimentary rocks. This trip will examine the structural, petrographic, sedimentological and economic aspects of these rocks.
