Microelement Geochemistry of Pyrites from the Shijia Gold Deposit in Northwest Guangxi
摘要
Abstract
This paper studies microelement geochemistry of the pyrite from the Shijia gold deposit through optical microscopy and electron probe microanalysis.The pyrite has a limited range of Co/Ni ratios,ranging from 1 to 10,indicating its hydrothermal origin.The with As-poor cores has complex origins,with some primarily of hydrothermal origin and the others being syngenetic pyrites altered by hydrothermal fluids.Au is present in solid solution (Au +),or contained in the edge of the arsenian pyrite or in the dissolution empty of early pyrite as nanoparticles of native Au.In combination with the deposit geologic characteristics,trace element geochemical characteristics and REE characteristics,it is suggested that the metallogenesis of the shijia gold deposit has a closed relationship with the surrounding rocks and diabase.关键词
