中文摘要: |
黑石砣矿床位于衡阳盆地北缘,是一个以Cu、Pb、Fe为主的多金属矿床。矿体产于断层破碎带中,近矿围岩具有强烈的热液蚀变作用。本文在详细阐述矿床地质特征和围岩蚀变特征基础上,划分蚀变期次、探究蚀变与成矿关系、指明找矿方向;认为该矿床围岩蚀变主要以硅化、黄铁矿化、重晶石化和钾化为主,矿化与围岩蚀变具有十分密切的关系,今后找矿应以4~11线,-200~+200m深度为主。 |
英文摘要: |
Located in the northern margin of the Hengyang basin, the Heishituo deposit is a polymetallic deposit dominated by Cu, Pb and Fe. The orebody occurs in the fault fracture zone, and the surrounding rock has strong hydrothermal alteration. Based on the detailed description of the geological characteristics of the deposit and the alteration characteristics of the surrounding rock, this paper divides the alteration stages, explores the relation between alteration and mineralization, and points out the prospecting direction. It is concluded that the alteration of surrounding rock is mainly silicification, pyritization, barite mineralization and potassium mineralization, and there is a very close relationship between mineralization and alteration of surrounding rock. In the future, ore prospecting should be mainly in the depth of 4~11 lines, -200~+200m. |
