| 摘 要： | 微细浸染型金矿床是我国主要的热液金矿床类型之一,空间上多分布于扬子地台周边地区,其产出受大地构造背景及地层、构造和一定的热动力条件的控制.我国该类型金矿床成矿作用总体具有如下特点:①矿化点多面广,但规模相对较小;②区域上金矿化常与Hg、Sb、As及U等元素低温热液矿床密切共(伴)生;③矿床形成具多期多阶段性,且其成因复杂多样;④成矿时代主要为印支晚期-燕山期.

| Abstract: | Micro-fine disseminated gold deposit is one of the most important hydrothermal deposit types in Cb ina. Most of th em are spatially distributed iu regions around the Yangtze platform, and their occurences are controlled by strata, structure and certain thermodynamic conditions in addition to tectonic backgrounds. The mineralization features of this type of gold deposits are as follows: (①) gold mineralization is distributed extensively in space, but the deposits are usually smaller in scale relatively; (②)regionally, gold mineralization often occurred in accompanion with low temperature hydrothermal deposits of Sb, As, Hg, U etc.; (③)the formation of the gold deposits experienced multiphases as well as polystages of mineralizing processes, and their origins are usually different and complex;and (④)the main metallogenic period is from late Indo-Chinese epoch to Yanshanian epoch. |
