Canada The Munising Group or Formation is a 1,700 feet (520 m) thick, white to light grey [ 1 ] Cambrian sedimentary unit that crops out in Michigan and (to a lesser extent) Ontario . At one end of its extent, it comprises a basal conglomerate overlain by the Chapel Rock Member and the Miners Castle Member; elsewhere, it comprises the Eau ...
Dunvegan Sandstone. The Dunvegan Formation is composed of marine, and deltaic sandstone with thin shale interbeds in the Peace River Country. East of Dunvegan, Alberta it is of marine origin, and in its western reaches in British Columbia it was deposited in a continental facies, where the sandstone becomes more conglomeratic.

Below the formation are the nearshore (beach and tidal zone) deposits of the Virgelle Sandstone, and above it is the marine Bearpaw Shale. Throughout the Campanian, the Two Medicine Formation was deposited between the western shoreline of the Late Cretaceous Interior Seaway and the eastward advancing margin of the Cordilleran Overthrust Belt .
Bedrock topography consists of two north north-east/south south-west trending ridges. Surficial material consists of some glacial till, thick marine clay, and freshwater and deltaic deposits grading from coarse sand to clay. Peat deposits in the bog proper are up to 6 metres (20 ft) thick.
The Campbellton Formation is the southernmost representative of the Gaspé Sandstones group [2] and can be divided into 6 facies associations (restricted lacustrine, marginal lacustrine, near-shore lacustrine, coastal-deltaic, sandy to gravelly alluvial plain, and gravelly proximal alluvial environments), and is nearly a kilometer thick.

Gething Formation is a stratigraphic unit of Lower Cretaceous age in the Western Canada Sedimentary Basin.It is present in northeastern British Columbia and western Alberta, and includes economically important coal deposits.
