| [摘 要] 本文通过对阿里住浪铜银矿区1:10000 地质填图和1:10000 构造地球化学测量,系统
总结了西藏阿里住浪铜银矿区构造地球化学特征,并得出以下几点认识:住浪矿区不同岩性中Ag、Cu、
As、Sb 浓度克拉克值和变异系数均较大,元素分布型式具对数双峰分布,表明这些元素卷入了成矿作
用;元素组合分析具成矿多阶段性,矿区主成矿元素组合为Cu、Ag,可作为找矿的指示元素;综合分析地
质和地球化学资料,在矿区圈定5 个构造地球化学异常区,其中玉号、芋号异常带具较好的找矿前景。 |

| Abstract:Geological mapping and tectono-geochemical survey at a scale of 1:10000 were conducted in the Zhulang copper-silver mining area of the
Ali area,Tibet. It is concluded that the concentration clark values and variation coefficients of elements Ag,Cu,As and Sb for different lithology are great,and the element distribution displays a logarithmic bimodal pattern. This is interpreted to indicate that these elements have been involved in mineralization. The element combination analysis shows the mineralization process has multiple stages. The main metallogenic element association is Cu and Ag,which can be used as the indicator elements for prospecting. Five tectonic geochemistry anomaly belts have been delineated based on the geological and geochemical analysis,among which the anomaly zones I and III show a better prospecting potential. |
