广西云开地区矿产特征及时空分布规律

Geological Features and Space-time Distribution of Mineral Deposits in the Yunkai Region,Guangxi

广西云开地区处于桂东南,是广西境内铅锌金银多金属重要成矿区域之一。区内构造复杂,岩浆活动强烈,侵入岩及其发育。矿产资源丰富,矿种类型较多。区域矿产受构造单元控制均呈北东向成群成带展布,各矿床(点)严格受其构造及岩性控制,并与岩浆活动密切相关。矿产具有成矿物质多来源、成矿作用多阶段、成矿时代多期性和长期性等规律。

The Yunkai mineralization zones within region in southeast Guangxi is one of important lead-zinc silver and gold the boundaries of Guangxi magmatism and abundant mineral resources. The mineral and characterized by complex structure, intense deposits are controlled by NE-trending structures and lithology and related closely to the magmatism. The ore mineral was derived from various sources, mineralization occurred in multiple phases and stages.
