such as the Banff Formation or Pekisko Formation, often separated by a Detrital Zone. It is correlated to the McMurray Formation in the Athabasca Oil Sands

evidence of an Archaean ancestry for the Bangweulu Block is provided by detrital zircons within the Mporokoso Group, which indicate a local source area
thin beds within peat swamps or mires. Like fireclays, ganisters are found within Carboniferous and other sedimentary strata independent of coal beds Thus
VISS are primary sedimentary structures formed by the interaction of detrital sediment with in situ plants. VISS provide physical evidence of vegetation s

Phosphorite, phosphate rock or rock phosphate is a non - detrital sedimentary rock which contains high amounts of phosphate minerals. The phosphate content

Garden member is a siliceous rock cemented with calcite and containing detrital phosphate. Mollusc bivalves account for up to 75 of the composition in
