山东五莲七宝山多金属矿区矿物学特征及黄铜矿LA-ICP-MS原位微量元素研究
Analysis on Mineralogical Characteristics and LA-ICP-MS in situ Trace Element in Qibaoshan Polymetallic Mining Area in Wulian County in Shandong Province
摘要
Abstract
Qibaoshan polymetallic mining area in Wulian county in Shandong province is a large scale mining area that integrates endogenous deposits,such as gold,silver,copper,lead,zinc and pyrite.It is a medi-um low temperature subvolcanic hydrothermal cryptodome breccia deposit.The exploration and research have a significant industrial and scientific value.Based on detailed petrography and mineralogy observa-tions,samples from different cryptodome breccia types in Qibaoshan polymetallic mining area have been analyzed.It is indicated that the diagenetic and metallogenic evolution in this area can be divided into six stages:pyrite-quartz stage,chalcopyrite-cuprite-chalcopyrite-pyrite-quartz stage,specularite±(py-rite)±(chalcopyrite)-quartz-carbonate stage,chalcopyrite-pyrite-galena-sphalerite-quartz stage,chalcopyrite-pyrite-quartz stage and late carbonate stage.As showed by situ trace element analysis of chalcopyrite,the content of Se in chalcopyrite in Jinxiantou mining area is higher than that in Yaotou min-ing area,while the contents of Ag,Pb,and Bi are lower.The formation temperatures of Jinxiantou mining area and Yaotou mining areas are lower than that in Hongshigang ore section,while the gold enrichment in Hongshihang mining area and Yaotou mining areas is higher than that in Jinxiantou mining area.关键词
