安徽宿松地区金矿构造控矿特征分析

Feature analysis on structural ore-controlling of gold deposits in Susong Area,Anhui Province

近年来宿松地区大别山宿松岩群变质岩中陆续发现多个构造蚀变岩型和石英脉型金矿床(点),金矿体受断裂构造控制明显。本区以往工作局限于普查找矿,对区内金矿床构造控矿特征方面的研究较少。本文通过对研究区内典型矿床(点)成矿地质特征和构造控矿特征进行分析,认为本区断裂构造是重要的控矿构造,金矿成矿与燕山期中酸性岩浆活动关系密切。

In recent years,several tectonic altered rock type and quartz vein type gold deposits(spots)have been discovered in the metamorphic rocks of the Susong Group of Dabie Mountain in Susong area.The gold ore bodies was obviously controlled by the fault structure.Previous work in this area was limited to prospecting,and there were few studies on the structural ore-controlling of gold deposits.Based on the analysis of the metallogenic geological features and ore-controlling structural of the typical deposits(spots)in the study area,it was considered that the fault structure is an important ore-controlling structure,and the gold mineralization is closely related to the Yanshanian intermediate acid magmatic activity.
