一个地区对金的某种特定类型矿床具有优越的成矿地质条件,从而使其集中分布,成为寻找该类床矿的有利地区,在国内外并不乏其例.但是,多种成因类型金矿床大量出现于有限范围之内的地区却为数甚少.本文所涉及的内蒙昭乌达盟南部及其邻区就是这样的一个特殊地区.在大约两万平方公里的范围内,岩金矿床和矿点见于不同时代,不同岩性的岩层(体)之中,包括了我国岩金矿床绝大部分成因类型,为一颇具特色的金矿成矿区.这里拟从总结金矿成矿的地区性特征入手,试探其成因,以利找矿勘探.
There is no lack of examples in this area both at home and abroad because of the favorable geological conditions for a certain type of gold deposit in a certain area in a certain area, A large number appear in a limited area within the region is very small.This article involves the southern Inner Mongolia Zhaowuda League and its neighboring areas is one such special area in about 20 thousand square kilometers range of rock gold deposits and ore It is found in the rock formations (bodies) of different ages and different lithologies, including most of the genetic types of the gold-gold deposits in our country, and is a rather special gold mineralization area. Here we will summarize the regional characteristics of gold mineralization Start, test its causes, to facilitate prospecting exploration.
