In this paper, we have analyzed lithofacies, sedimentary facies, sequence stratigraphy, and coal accumulation of the Lower Cretaceous in the Baiyinhua Sag of the Erlian Basin. The coal seams, which were developed from the littoral-shallow lacustrine and braided fluvial delta plain environments, were mainly formed in the late lowstand systems tract and late transgressive systems tract.
