壤塘地区遥感统计与成矿预测

Remote Sensing Statistic and Metallogenetic Prediction in Rangtang Area

本文以遥感统计为主要依据,结合区域大地构造和地质、化探资料,对该区进行成矿预测分析。该区处于川西北金三角区,成矿条件有利,已发现金木达,南木达,代隆等多个金矿床。本文圈出四个主要成矿远景区。

Based on the remote sensing interpretation, combined with regional geotectology and geology, geochemical exploration data, analyzed metallogenetic prediction of the area. The area located in Rangtang metallogenic belt of Gold Triangle area in northwest of Sichuan province, which is in the tectonomagrnatic belt. For the advantaged metallogenetic condition, there have been found several gold deposits, such as Jinmuda, Nanmuda, Dailong and so on. By using the system software of metallogenetic prediction, which developed by Gold Party, got the statistic of the density of linear feature and ring-like structure and the density of point of intersection of linear-ring structure. Combined with the main metallogenetic prospective areas which marked by the large numbers of geological information, gave the supervised suggestion for the prospecting work of the area.
