Then on the basis of study results about regional geology, ophiolite,structure,and seismic depth-sounding in the Qinghai-Tibet plateau and its adjacent areas, this paper promotes a new model to interpret tectonics.This new model thinks that in this large area there was not simple B-type subduction which is accompanied with ocean-floor spreading at mid-ocean ridges to form ocean basins appearing as new oceans and new ocean plates,but intercontinental seas due to ocean-floor spreading,obduction of ophiolite tectonic slice as oceanic crust slabs and complex A-type subduction of continental lithosphere slabs.

The conception, studied objects and basic constituents of non-Smith strata are elaborated from theory level: Non-Smithian strata are the strata that have undergone mixing of different degrees, thus were deformed, metamorphosed and displaced into disorder totally or partially. They are the disorder parts in orogenic belts. Melange is the solo studied object of non- Smithian stratigraphy. The slices in melange is one of the basic constituents of non- Smithian strata, and also one of the basic units in the non-Smithian mapping. The slices used in this paper refer to blocks divided by small-scale tectonic boundaries and have certain constitutes. Superslices used in this paper refer to a set of slice association with similar tectonic deformation bounded by large-scale tectonic mixing.
从理论上阐述了非史密斯地层的概念、研究对象和基本构件:非史密斯地层(non-Smithian strata)是指那些经历过不同程度的混杂建造,并经历了变位,变形、变质,全部无序或部分无序的地层,主要指造山带地层中的无序部分;混杂岩是非史密斯地层的唯一研究对象;混杂岩中的构造岩片是非史密斯地层基本构件之一,亦是非史密斯地层和地质填图基本单位之一,岩片是指以构造拼合边界所分割的具有一定物质构成的地质体;物质建造形成于同一大的构造旋回期(如晋宁期、加里东期、海西期等)、亲源关系密切、大致经历了相似变形、变质历程的一套岩片组合体被称之为超岩片。

Secondly, study on bleaching of sandstone based on field characteristics, petrography, geochemistry and compared with other sandstone related, combined with geological setting of gas seepage in the area, reveals that natural gas leakage is responsible for bleaching of the sandstone on top of Yan\'an formation. The bleaching resulted from interaction between the reductive fluid and the rock. At the same time the bleaching suggests that the northeast of basin has experienced large scale gas seepage.
