贵州独山锑矿田构造控矿作用分析
|
摘要
独山锑矿田位于贵州南部,扬子古陆的西南缘与雪峰山隆起的嵌接部、黔南坳陷东部独山鼻状凸起中。以区内主要构造为对象,分析其区域构造背景、地质特征及其与成矿的关系,总结构造控矿模式,在此基础上分析本区找矿潜力。认为区内主干断裂可以分为三级:Ⅰ级构造不仅形成地垒骨架,同时也联合Ⅱ级构造控制了矿田的分布,Ⅲ级构造则是本区的主要控矿构造。矿田主要锑矿床形成于燕山中晚期陆内造山挤压向板内伸展转换的环境;独山锑矿田具有形成大型矿集区的地质构造条件,找矿潜力巨大。
Dushan antimony orefield is located in the southern of Guizhou,the ministry scarf of the southwest margin of Yangzi land block and the embedded part of Xuefeng Mountain uplift,the Dushan nose bulge in the east of Qiannan depression.Taking the main tectonic in the area as the research object,this paper analyzes the regional tectonic background geological characteristics and their relationship with mineralization,and summarizes the tectonic ore-controlling model.On the basis of those above,analyzing the prospecting potential of this area,it is concluded that the main faults in the area can be divided into three grades.The gradeⅠstructure not only forms the framework of the horst,but also controls the distribution of the ore field combining the grade II structure.The gradeⅢstructures are the main ore-controlling faults in this area.The main antimony deposits in the orefield were formed in the environment conversion from intracontinental orogenic compression to intraplate extension in the Middle and Late Yanshanian Period.Dushan antimony orefield has the geological structure conditions for forming large ore-gathering areas and has great prospecting potential.
