摘要

Abstract

Sequence stratigraphical analysis was applied to the Upper Carboniferous-Lower Permian sedimentary succession of the northeastern Ordos Basin,north China based on data acquired from ten entire logging curves and eight outcrops.The facies framework of the lithostratigraphical unit,the Taiyuan Formation comprises seven facies in two facies associations,varying from fluvio-delta to shelf-barrier islands.The facies are presented within a chronostratigraphical framework,linked by systems tract,which in turn are limited by flooding surfaces and sequence boundaries.Six third-order depositional sequences are recognised,bounded by six type 2 unconformities.An upwards-shallowing epicontinentai sea sedimentary model is created,which consists of a sandstone,coal seam and carbonate succession.
