Book excerpt: In this study, the sequence stratigraphic analysis of some coal seams in the Lower Cretaceous Mannville Group of Alberta is presented within a hierarchical framework of three orders of depositional sequences. The analysis is based on an integrated database of lithostratigraphy, sedimentology, palynology, organic petrology, and geochemistry. A unique aspect of this study is an emphasis on the following key stratigraphic features of coal seams in analyzing their sequence stratigraphic relations: patterns of coal-seam splits and their relation to transgressive & regressive cycles; characterizing the transgressive or regressive natures of coal seams using typical signatures in vertical changes in petrological, geochemical, and palynological parameters; and recognizing multiple transgressive & regressive cycles and subtle unconformities within a thick, regionally extensive coal seam.
