For giving an explaintion of strong transmogrification but feebleness metamorphism of and their corresponding relation of the Triassic stratum in Songpan-Ganzi area and opening out the temperature and stress condition, this paper summarized study production of predecessors, and put forward 5 conclusions about Songpan-Ganzi area Triassic main lithology(slate, sandrock,and blastopsammitic) through field geological investigation , actual measurement section plane study and combining indoor slice identification , electron probing and fluid enclosure testing analysis:1.Field outcrop strongly transmogrification, and often developed same cleavages(S1) erection or approximately erection 'B'fold and symmetry similituded fold. 2.The metamorphosed mineral combination is simple, and the typical metamorphosed mineral combination is Al+Chl+Ser+Cc+Q, etc. The metamorphosed mineral develops mainly along the cleavages of the territorial cleavages faces(S1), bearing territorial dynamic metamorphism character and belonging to the lawsonite-albite-chlorite face of slightly metamorphism. 3.Territorial metamorphism P-T change focus on T:180～200oC, P:1～2kbar

为了对松潘-甘孜地区三叠系强变形浅变质的特征及变质与变形的对应关系作出解释，揭示变质与变形的温-压条件，本论文总结前人研究成果，通过野外地质调查和实测剖面研究，结合室内薄片鉴定、电子探针和流体包裹体测试分析，对松潘-甘孜地区三叠系主体岩性(板岩、砂板岩、变质砂岩及千枚岩)的变质作用得出5 个认识结论：1、整个松潘-甘孜地区经受了自北向南的强大挤压；2、变质矿物组合简单，除雏晶黑云母外，典型的变质矿物组合为Al+Chl+Ser+Cc+Q等，变质矿物主要沿区域性劈理面(S1)的劈理域发育，具有区域动力变质作用特征，属于低级变质作用中的硬柱石-钠长石-绿泥石相；3、区域变质作用P-T 变化集中在T：180～200oC，P：1～2kbar

The authors believe that the diversification of rock zonation and lithology of these high pressure rocks can be attributed to the metasomatism that took place between deep melt and ultrabasic rocks in the subduction zone, and thus propose a hypothesis of subduction melt metasomatism to explain jadeite formation.

笔者认为俯冲带中形成的深部熔体与超基性岩之间的交代变质是导致岩石分带和岩性多样化的根本原因，提出了俯冲带熔体交代成因说，认为俯冲带、深部流体和超基性岩体是形成翡翠及其过渡品种的3个必要条件，并因此指出在人工合成过程中引入流体相很可能是降低实验条件的苛刻程度、从而合成出真正具有商业意义的翡翠的途径。

Since the well-log data interpretation is a basic step of the joint inversion, the paper studied the inversion algorithms of two-type problems of lithology and reser voir parameters using well-log data by ANNs and examined the advantages and practi cality of the technique with a large amount of real data.

考虑到测井资料是联合反演中的基本的一步，本文研究了应用人工神经网络根据测井资料预测岩性和储层参数这两类问题的数据驱动的反演算法，并以大量的实际资料处理结果，证实了该方法的实用性和优越性。
