贵州灰家堡金矿田成矿与蚀变元素迁移
Study on mineralization and migration of alteration elements in Huijiabao gold field, southwestern Guizhou, China
摘要
Abstract
The Shuiyindong deposit and Taipingdong deposit in the Huijiabao ore field are selected to study the migration regularity and mode of elements in the process of wallrock alteration of the Carlin-type gold deposit and to explore the internal relationship between the alteration and gold mineralization.Study of typical surrounding rocks,mineralization rocks,ore petrographic characteristics and corresponding grant mass balance equation shows that the type of wallrock alteration corresponding to the metallogenic stage of the Carlin-type gold deposit is consistent with the element migration law revealed by calculation.Geochemical thermodynamics calculation suggests that gold mainly migrates in the form of AuHS0 complex in the ore-forming solution.It shows that the wallrock alteration in different metallogenic stages promotes the migration of major ore-forming materials in the Carlin-type gold deposits,and then precipitates and enriches the gold ore formation.关键词
