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.

而后又以青藏高原及邻区为例，根据区域地质、蛇绿岩和地质构造研究的成果，特别是地震测深研究的成果，详细地论证了本区不存在有大洋中脊扩张成为大洋盆地的新大洋和大洋板块简单的B型俯冲模式，但存在有海底扩张的陆间海和海洋地壳板片的仰冲以及大陆岩石圈板片复杂的A型俯冲新模式。

The ultramafic rocks outcropped at the Altyn region are all harzburgites. Remant grains of primary minerals have melted residual texture and elastic deformation texture under high temperature and pressure. The whole-rock analyses show their low TiO〓 contents (0.01～0.04%), low Al, Ca and high MgO contents and wide Mg〓 range (89.35～95.57). Rare earth patterns have two types, namely tabacco pipe-shped and LREE-shaped, of which the former is often seen. The chondrite-nomalized Yb values of these analyses are all lower than 1. The spinels have low Ti and high Cr content and most spinels have Cr# higher than 60. All of the above characteristics show that the ultramafic rocks in the Altyn fault zone are components of metmorphic peridotites of ophiolite from depleted mantle source and most ophiolites from this zone belong to supra-subduction zone type ophiolite with a few mid-ocean ridge basalt type.

阿尔金露头区的超基性岩全为方辉橄榄岩，残余的新鲜矿物颗粒发育有熔融残余结构和高温高压下塑性变形结构，全岩分析显示样品TiO〓的含量低，为0.01～0.04％，具有低的Al和Ca，MgO含量高，Mg〓为89.35～95.57；稀土配分型式有两种，即烟斗型和LREE亏损型，前者占绝大多数，Yb球粒陨石标准化后的值全都小于1；尖晶石低Ti高Cr，大部分尖晶石的Cr〓大于60，上述特征说明阿尔金超基性岩是蛇绿岩的地幔橄榄岩成员，来自亏损的地幔源区，阿尔金蛇绿岩大多属于俯冲带之上型蛇绿岩，有少量的大洋中脊型蛇绿岩。

Selecting two ophiolite zones (namely Hongliugou-Lapeiquan ophiolite zone and Sulamutage ophiolite zone) respectively located within the southern and northern part of the Altyn fault and based on analysis of field geology characteristics and geochemistry, this paper recognized the rock types (mainly mafic and ultramafic rocks) within the melanges and subdivided each lithological unit based on tectonic environment.
