Milankovitch Paleoclimatic, Tectonic, and Sedimentary Signals in Late Permian-Early Triassic Fluvial-Lacustrine Records, Bogda Mountains, Nw China
Abstract
Non-marine cyclostratigraphic records are a manifestation of repetitive changes of ancient continental environmental, paleoclimatic, tectonic, and ecosystem conditions. Stratigraphic sections in Bogda Mountains, NW China, provide detailed records of the late Permian-Early Triassic terrestrial paleoenvironmental and paleoclimatic evolution at the paleo-mid-latitude of NE Pangea. Cycles of fluvial-lacustrine environmental shifts are related to variable forcing mechanisms and may have been influenced by various Milankovitch climatic forcings. This study is to identify the Milankovitch signals in our records and characterize the controlling factors of cyclic sedimentation in the terrestrial rift basin and temporal evolution. Methods include gamma and spectral analyses of lithological and depositional environment variations.
