"The overall objective of this study is to understand physical and chemical responses of Earth Systems to environmental and climatic perturbations of diverse magnitudes and time scales in Bogda Mountains, NE Pangea. Field investigations, petrographic observations, and geochemical analyses have been used to interpret paleoenvironment and paleoclimate in cm-m-scale high-order cycles (HCs: 0.1-100 kyrs), low-order cycles (LCs: 1-10 Myr), and critical events of late Paleozoic ice age (LPIA: 320-260 Myr ago). Four organo-facies are one-to-one correlated with the four lithofacies in the meter-scale HCs, suggesting litho- and organo-facies are genetically linked and fundamentally controlled by environmental changes associated with lake contraction and extension. The coincidence of climatic changes in mid-latitude northeast Pangea and Gondwanan glacial-interglacial in mid Sakmarian-early Kungurian provides clues that glaciation may have exerted a substantial control on climatic changes in mid-latitude Northern Hemisphere"--Abstract, page iv.
