| 摘 要： | 本文叙述了秦岭大巴山地区中——酸性浅成——超浅成侵入——爆破“杂”岩体的地质特征及其分布;叙述了与岩体有成生联系的斑(玢)岩型、矽卡岩型、爆破(隐爆——坍塌)角砾岩型、构造蚀变岩型、热液脉型等类型金矿的地质特征;总结了岩体的成矿模式,同时指出了矿床类型和共(伴)生元素的成矿系列;指出分布在秦巴地区的5个印支期——燕山期岩体带中的21个小岩体群,其中数百个小岩体及其附近有找到多种类型金矿的可能,预测其找矿前景乐观,金矿资源潜力很大。

| Abstract: | There are many small-sized hypabyssal intermediate-acidity intrusives which are distributed in the Qinling-Dabashan area. They have genetic relations with all kinds of gold ores in the area. In this paper, the writer discusses the geological characteristics of the gold ores, and summarizes the metallogenic models which is relative to the small-sized intrusives, the gold ore types and the metallogenic series of coexisting(accompanying)minerals. The writer believes that there are a great number of potential resources for prospecting multiple kinds of gold ores in the 21 small-sized rock mass groups from the five rock belts formed during the Indo-Chinese and Yanshanian epoches in the Qinling-Dabashan area. |
