通过对西北地区大量陆相侏罗系地质剖面的研究，依据古构造格架、基底特征、构造变形、岩浆活动、沉积建造特征、古生物群特征以及地层发育程度和接触关系等，把西北地区陆相侏罗系划分为１０个地层区和７个地层分区；并在地层区划的基础上讨论了侏罗纪岩相古地理及石油、煤炭等沉积矿产分布规律
Based on the study of a large number of continental Jurassic geological profiles in Northwest China, based on the paleostructural framework, basement features, tectonic deformation, magmatic activity, sedimentary characteristics, paleontological features, stratigraphic development and contact, The Jurassic system is divided into 10 stratigraphic zones and 7 stratigraphic zones. Based on the stratigraphic division, the Jurassic lithofacies paleogeography and the distribution of sedimentary minerals such as oil and coal are discussed
