桐柏银洞坡金矿床构造形迹研究

Research on Structural Trace of Gold Deposit of Tongbai Yindongpo Gold Mine

银洞坡金矿是伴生有银、铅锌多金属的超大型金矿床;该矿床严格受构造形迹和地层的双重控制;构造形迹是控制矿床的形成、发展和迭加改造的主要因素;通过对该区构造形迹研究,从力学应力侧面反映该区现存构造从先期产生、中期发展、后期迭加改造的动态变化过程以及与成矿的关系。

Yindongpo Gold Mine is a large gold deposit that associates with silver, lead and zinc. This deposit is strictly controlled by structural trace and stratum. The structural trace is the main factor that controls formation, development and superposition reconstruction of the deposit. Through research on the structural trace of this district, the dynamic changing procedures of the existing structure in this district from production in early stage, development in midstage, to superposition reconstruction in late stage are reflected by the mechanics stress. The relations between the dynamic changing procedures and mineral forming are also presented.
