江西冷水坑银铅锌矿田构造地球化学的若干问题

本文重点对冷水坑银铅锌矿田构造发育特征和构造地球化学的若干问题进行了初步探讨。运用裂隙统计、显微构造和组构分析方法对矿田NE向、NW向和近EW向断裂的力学性质和活动方式作了概略性论述。研究了银路岭矿床三个构造地球化学剖面的分析结果,其中主要成矿元素和伴生元素的分布和丰度变化与构造发育的关系,显示出本区构造地球化学场具有一定的分布规律。矿田F_1断裂是有一定区域意义的重要的成岩成矿和控岩控矿断裂,本次工作中选择了茶田剖面对F_1断裂带构造地球化学特征进行了初步探讨。

SOME PROBLEMS OF TECTONO-GEOCHEMISTRY IN LENSHU IKENG Ag-Pb-Zn ORE FIELD,JIANGXI PROVINCE,CHINA

In this paper the characteristics of development of structure in the Lengshuikeng Ag—Pb—Zn ore field and some problems of tectono—geochemistry are mainly discussed. By means of joints' statistical analysis,microstructure analysis and fabric analysis,the mechanical natures and manner of action of NE—,NW—and EW—trending fanlts in the ore field are also discussed. According to the analysis of three sections of tectono—geochemistry in the Yinluling ore deposit, the relation between the distribution and abundance variation of main ore-forming elements and associated elements and development of structure shows that the tectono—geochemical field possesses definite regularities. The fault F_1 is regional and important rock—and ore—forming and rock—and ore—controlling structure in the ore field. In this work the fault F_1 zone at the Chatian section is preliminarily discussed on the features of tectono—geochemistry.
