摘要
本文通过成矿区域背景的分析及矿床地质特征的研究,阐明了蚀变作用类型及其关系,总结了蚀变成矿作用过程中元素的迁移富集规律。综合研究结果表明,该矿床是以珍珠岩及熔结凝灰岩为成矿原岩,在一定的温度和压力条件下,经多期次蚀变成矿作用改造而形成的矿床。
On the basis of detailed analysis of the regional metallogenic background and the geological characteristics of the bentonite deposits, the alteration types and the relations among them are elaborated in the paper. furthermore,the richment regularities of elements during the process of alterated ore-forming are summarized. Comprehensive studied results indicate that this bentonite deposits formed at special temperature and presure through different stages of alterated mineralization.
