Trace Elements in Pyrites and Their Implication for Hydrothermal Ore-forming Process in Longshan Gold-antimony Deposits, Hunan, China
摘要
Abstract
Trace elements content in pyrite can give information of element occurrence and trace hydrothermal ore-forming processes. Many kinds of trace elements in pyrites from slate, altered slate and ore in Longshan gold-antimony deposits were measured using EPMA. The analysis data suggest that Au in sedimentary pyrites are mainly nano particles, whereas Au in hydrothermal pyrites are solid solution as well as nano. In sedimentary pyrites , Ni, Sb, Mn, Te might be in form of solid solution, but As, Pb, Zn, Cu, Ag mineral inclusions. In hydrothermal pyrites, As, Sb, Mn, Te might be in form of solid solution, but Co, Ni, Pb, Zn, Cu, Ag mineral inclusions. Longshan gold-antimony deposits had been underwent two mineralization epochs. During earlier epoch , it occurred lower intensity Au-Pb-Cu-W mineralization related to deep high Ni magmatic fluids. During later epoch, it occurred Au-Sb mineralization closely related to meteoric circulation. The later mineralization epoch, as the main mineralization period, can be divided into four stages; micro gold stage, submicro gold-stibnite stage, invisible gold-stibnite stage, and stibnite stage.关键词
