摘要
羊石坑汞矿床位于四川省秀山县境內,是近年新勘探的一个大型汞矿床。以细脉浸染型为特征而区别于我国其他大型汞矿床。本文通过对该矿床构造展布特征及不同构造部位矿物、元素和同位素的分布、分配特征的研究,揭示了该矿床矿物、元素和同位素等的分布、分配规律及其与构造带的关系,从而阐明了矿床的构造控矿规律和有关元素在构造作用下的迁移富集特征。本文还从实验角度对矿床形成的构造改造机制进行了初步模拟,为矿床形成、分布规律提供了实验依据。
The Yangshikeng mercury deposit, located in Xiushan County, Sichuan Province, is a superlarge mercury deposit discovered in recent years. Its difference from other large -scale mercury deposits in China lies in the fact that this deposit is of the stockwork-disseminated type. Studies of the structural features of the deposit and of the distribution features of minerals, ore-forming elements and stable isotopes in different structural positions have revealed the structural control over the metallogenesis of this deposit and the regularities governing the migration and concentration of ore-forming elements in response to tcctonism. Furthermore, a high T-P tectono-geochemical model experiment was done on the mechanism of tectonic control over the deposit and the results are sensitive enough to explain the metallogenic origin of the deposit and its distribution.
