川西中酸性侵入岩位于雅砻江和金沙江流域的东侧,该区是太平洋、欧亚及大西洋成矿域相汇合的三角形地带,是解决全球古构造的重要地区,为中外地质学者所重视。但因地处横断山区,研究程度极低。近20年来,四川省地质矿产局及有关单位开展了1:100万及1:20万的区调和矿产普遍与科研工作,初步认为本区可成为我国有希望的Ⅰ级成矿远景区。本文根据近年来在该区所获中酸性侵入岩的硅酸盐分析成果,试图用数学地质方法进行成矿予测的探讨,以圈定其成矿远景区,供有关单位参考和利用,不妥之处,欢迎批评指正。
The intermediate-acidic intrusive rocks in western Sichuan are located to the east of the Yalong River and the Jinsha River. This zone is a triangular zone where the Pacific, Eurasian and Atlantic mineralization meet. It is an important area for solving global paleotectonics and is valued by both Chinese and foreign geologists . However, due to being located in Hengduan Mountains, the research level is very low. In the recent 20 years, the Bureau of Geology and Mineral Resources of Sichuan Province and other related units have carried out the universal and scientific research on the 1: 1000000 and 1: 200000 regional reconciliations of mineral resources. It is preliminarily believed that this region can become a promising Class I prospecting prospect in China. Based on the results of silicate analysis of moderately acidic intrusive rocks obtained in this area in recent years, this paper attempts to explore the mineralization prediction by using mathematical geologic methods to delineate its metallogenic prospect for reference and utilization by relevant units Department, welcome criticism correction.
