蚀变围岩及其找矿意义

Altered Country Rocks and Their Ore-finding Significance

蚀变围岩是在热液作用影响下,使矿物成分、化学成分及结构、构造发生变化的岩石。这种蚀变常见于热液矿床的周围,因此,研究蚀变围岩对于热液矿床成因、成矿过程元素迁移和富集规律、指导找矿有着极其重要的意义。

The altered country rock is one of deformational rocks which have changed from the mineral components, chemical composition and structures of the rocks under the influence of hydrothermal process. The alteration is often discovered around the hydrothermal deposits. Therefore, researching the alteration around the country rock is of vital importance for probing into the genesis of hydrothermal deposits, the element migration and enrichment law in the ore forming process and the ore-finding targets.
