Element geochemistry of ore-bearing rock series in the Getang gold deposit, Guizhou Province
摘要
Abstract
The Getang gold deposit in Guizhou Province has large reserves, high grade, special formation circumstances, and typical double ore-controlling characteristics: one is the horizon, and the other is the karst unconformity. There are varied (silicification, tectonic) breccias, low-temperature hydrothermal minerals (realgar, orpiment, stibnite and fluorite etc.) and wall rock alteration mineral assemblages in the ore-bearing rock of the Getang gold deposit. Its hydrothermal ore-forming stage can be divided into two metallogenic stages. The first is the main ore-forming stage—pyrite stage and the second is the late ore-forming stage—fluorite stage. Based on a systematic study of trace elements (Co/Ni and Th/U), REE, sulfur isotopes (pyrite and stibnite) composition characteristics of single minerals (pyrite and fluorite) and ore -bearing rocks (horizon), the authors tentatively hold that the Getang gold deposit possesses normal seawater sedimentation characteristics, its ore-bearing layer was developed in a marine and poor oxygen environment, and the initial ore—forming material was probably related to Emeishan basalt activity, but late deep material may have had contributions to mineralization for further enrichment of Au.关键词
