Types of Sedimentary Facies of Palace Area in Songliao Basin

The palace is located in the Songliao Basin, southeast regional uplift Palace rift, Denglouku off during the deposition of Au transition period for the basin, with more than provenance, short distance transport, Tianpingbuqi characteristics, Quantou deposition during the period of depression basin, with settlement rate, stable sedimentary environment and so on. According to the results of previous research and heavy mineral analysis to determine the palace area Denglouku Quantou northeast direction during the deposition source and southern elm Dehui subject matter Fulongquan provenance affects two provenances, braided river Delta meandering river depositional environment. Total identify four kinds of sedimentary facies, seven kinds subfacies and 14 types of sedimentary microfacies.
