The Cambrian spanned from to million years ago and is the first period of the Paleozoic era of the Phanerozoic. The Cambrian marked a boom in evolution in an event known as the Cambrian explosion in which the largest number of creatures evolved in any single period of the history of the Earth. Creatures like algae evolved, but the most ubiquitous of that period were the armored. Cretaceous fluvial strata in the Moose River Basin of Ontario, Canada, as a source of kaolin for paper and ceramic industries January Applied Clay Science 16(1) The Hudson Bay-Arctic Lowlands is a landform region of Canada, located more specifically in Ontario, Quebec, Manitoba, Yukon, Northwest Territories, and Nunavut. This region formed in the Paleozoic Era, when the enormous weight of a glacier sunk the Canadian Shield and the area became lowlands when the glaciers retreated. Western Canada during the Mesozoic The Mesozoic extends over million years from the beginning of the Triassic ( Ma) to the end of the Cretaceous (65 Ma). It was a particularly important period for the geology of western Canada.
Nicolas, M.P.N. and Lavoie, D. Oil shale and reservoir rocks of the Hudson Bay Lowland, northeastern Manitoba (part of NTS 54); in Report of Activities , Manitoba Innovation, Energy and Mines, Manitoba Geological Survey, p. – Summary The Hudson Bay and Foxe Basins Project is in its fourth and final year. The Trout Lake deposit ( ± 1 Ma) is a rhyolite-hosted, bimodal-mafic, volcanogenic massive sulfide (VMS) deposit. It is one of the largest VMS deposits in the Flin Flon mining district, containing Mt of Cu-Zn rich ore. The deposit underwent greenschist facies metamorphism and polyphase synvolcanic to postvolcanic hydrothermal alteration. morphology and depositional environment. Unlike most other coal deposits in Saskatchewan, which are relatively thin (less than a few metres), regionally extensive paralic-type deposits, the Hudson Bay area coal discoveries are more localized and have far greater thicknesses of up to m (including partings). Prior to retirement Darrel G.F. Long worked in the PhD Program in Mineral Deposits and Precambrian Geology, Laurentian University. Darrel does research in Fluvial Sedimentology, Stratigraphy.

These deposits represent the diverse fluvial to deltaic and lacustrine environments that existed within the basins. The rifting ended early in the Jurassic with the onset of regional volcanism and intrusion of diabase dikes and sills.
