试谈上海地区找金方向

THE DIRECTION OF PROSPECTING GOLD DEPOSIT IN SHANGHAI AREA

本文在分析上海地区区域控矿条件(前震旦系金山群、区域深断裂及燕山晚期中酸性小侵入体)的基础上,以区内张堰铜银矿与浙江治岭头金银矿对比,显示两者在区域地质背景、矿床特征和成因及其矿质来源等方面均存在某些相似性。从而提出在区内金山群、深断裂和小侵入体“三位一体”地段寻找金矿的设想。

This paper is based on the analysis of the condition of the regional metallogeny (Presinian Jinshan group, regional deep fault and the late Yanshanian period infermediate-acidic small intrusion) in Shanghai. A comparison is made between Changyan Cu-Ag deposit in this area and Zhileng Tou Au-Ag deposit in Zhejiang province, and some similarities in regional geological settng, the characteristic of deposit, the origin and the resource of material are shown. Therefore, this paper proposes that the prospecting of gold deposit in this area should be at the site of 'three-in-one' of Jinshan group, deep faults and small intrusions.
