The rock assemblage and geochemisty of the sedimentary rocks indicate that the Xiong'er Group formed in a passive continental margin and it was mainly a marine facies when lava erupted. Therefore the paleogeographic environment of the Xiong'er Group evolved from continental facies to marine facies then to continental facies again.

沉积岩的岩石学和地球化学特征表明熊耳群形成于被动大陆边缘的构造环境，结合火山岩的结构、构造特征，表明火山喷发的主体环境是海相，经历了陆相到海相再到陆相的演变过程，即：伴随着裂谷的发育、地面沉降和海水的侵入，以及随着火山喷发的进行最后又高出海面暴露于地表的全过程。

In order to seek the favorable reservoir, thorough research on its lithofacies paleographic, sedimentary faci-es, petrologic property, pore type and petrophysical property is carried out in Chang 6 to Chang 8 reservoirs of the Triassic period according to prospects for oil and gas exploration and development at Longdong region in Eerduois Basin.

针对鄂尔多斯盆地陇东地区勘探开发前景，为寻找有利储层，对其三叠系延长组长6—长8储层的岩相古地理及沉积相特征、岩石学特征、孔隙类型及物性特征进行了深入研究，并讨论了物性与砂体成因的关系。

The petrology and geochemistry indicate that the protoliths of aluminum-rich gneisses are aluminum-rich pelitic and pelitic arenaceous sedimentary rocks, the protoliths of basic granulites are continental tholeiitic basalts. Therefore, the khondalite series may be produced at continental margin.

岩石学及地球化学的初步研究表明富铝的片麻岩的原岩为富铝的泥质和泥砂质沉积岩，所夹基性麻粒岩的原岩可能为大陆拉斑玄武岩，这套孔兹岩系的原岩可能形成于大陆边缘环境。

The types of sedimentary organic facies are determined by a synthetical study of the hydrocarbon source rock's features of organic petrographical, organic geochemistry and sedimentology.
