The fault clay of some principal faults,including Altun,Changrna and Maornaoshan faults,along the northeastern border of Qinghai--Xizang Plateau is first studied. On the basis of the comprehensive analyses of the inner structures, country rock composition,fault clay thickness and quartz grain surface features within a faultzone,the fault activity ages and ways as well as the depth of fault gouges are discussed. The surface corrosiondegrees of quartz grains can be classified into six types and each type has a corresponding age. The division standards of fault activity natures are proposed,by which the stick-slip and creep slip parts of a fault zone can be divided. Through the infrared spectroscopic analysis and rare earth element analysis I it is considered that the faultgouge formed at about 10 km depth within the crust.

本文对青藏高原东北缘一些主要断裂(包括阿尔金、昌马、毛毛山等断裂)的断层泥首次进行了研究。在对断裂带的内部结构、围岩成分、断层泥的厚度及石英颗粒表面特征等综合分析的基础上对断裂的活动年代、活动方式及断层泥形成的深度进行了讨论。石英颗粒表面上溶蚀程度(颗粒表面的光滑程度、凹凸现象及孔洞发育情况)可划分为6种类型并且每种类型都有相应的年代。根据断裂的粘滑、蠕滑特征,对该区的各活动断裂进行了粘滑段与蠕滑段的划分。用红外光谱与稀土元素的分析结果,算得断层泥形成的深度在地壳10km范围内。

This paper expounds the geologic setting, surface distribution, subsurface extension and tectonite features of Shuitianba fault, then a nallyses the fault properties and its formatiom mechanism. By way of studying the faulted dynamics and kinematics and measuring the activity ages, it is indicated that Shuitianba fault is in week activating or non - activating state and not likely to occurs strong deformation effect inducing moderately strong earthquake after the Three Gorges engineering is in operation....

This paper expounds the geologic setting, surface distribution, subsurface extension and tectonite features of Shuitianba fault, then a nallyses the fault properties and its formatiom mechanism. By way of studying the faulted dynamics and kinematics and measuring the activity ages, it is indicated that Shuitianba fault is in week activating or non - activating state and not likely to occurs strong deformation effect inducing moderately strong earthquake after the Three Gorges engineering is in operation. From this it is concluded that Shuitianba fault will not constitute a threat on the Three Corges engineering.

本文主要介绍三峡水田坝断裂的地质背景,地表分布、地下延伸和构造岩特征,分析其性质及形成机理。通过断层动力学、运动学研究及其活动年龄的测定,表明水田坝断裂现在活动微弱或不活动,三峡工程运行后,该断裂不会发生较大的变形效应而诱发中强地震,该断裂对三峡工程不构成威胁.

Based upon the background and evolution of Xionger Fault Basin tectonic setting the magmatic activity ages were accurately dated (for indosinian Epoch 208.5±6.2Ma,Yanshan Epoch 121.6±3.9 Ma)using U-Pb dilution method, the 40Ar- 39Ar plateau age dated for the upper part of Xionger Group yield 206.55 Ma and its isochrone age dated 207.52±2.56 Ma, indicating thermal disturbunce age, the internal isochron of Sm-Nd method dated for alteration minerals of gold deposits in Beiling Gold...

Based upon the background and evolution of Xionger Fault Basin tectonic setting the magmatic activity ages were accurately dated (for indosinian Epoch 208.5±6.2Ma,Yanshan Epoch 121.6±3.9 Ma)using U-Pb dilution method, the 40Ar- 39Ar plateau age dated for the upper part of Xionger Group yield 206.55 Ma and its isochrone age dated 207.52±2.56 Ma, indicating thermal disturbunce age, the internal isochron of Sm-Nd method dated for alteration minerals of gold deposits in Beiling Gold Mine and Chen Huzigou Gold Mine yield an age 186±2 Ma. All the dating ages are larger than the age of the Yanshan Epoch and are approached to the age of Indosinian Epoch, showing the coupling character of isotopic geochronology between magmatic activities,thermal tectonic events and mineralization.

在熊耳裂陷构造环境背景和演化的基础上 ,应用U Pb稀释法精确确定岩浆活动年龄 (印支期 2 0 8.5±6 .2Ma ,燕山期 12 1.6± 3.9Ma) ;熊耳群上部安山岩40 Ar 3 9Ar法坪年龄 2 0 6 .5 5Ma ,等时线年龄 2 0 7.5 2± 2 .5 6Ma ,指示热扰动年龄 ;北岭金矿、陈胡子沟金矿蚀变矿物Sm Nd法内部等时线年龄 186± 2Ma。这些年龄大于燕山期 ,而与印支期相近 ,显示了印支期岩浆活动、热构造事件和有关成矿作用的耦合性。
