Abstract

Clay mineral assemblages Alberta Plains are a product of the original peat-accumulating and adjacent fluvial depositional envrionments. In the Highvale area, acidic conditions promoted by the accumulation and humification of thick peats were conductive to the diagenetic mineralization of kaolinite from parent volcanic ash. Volcanic ash horizons from adjacent environments at Whitewood and Genesee, which were under a greater influence of fluvial activity and fresh water, are composed predominantly of smectite and display a diversity of detrital minerals. -from Authors
