湖南铜山岭铜多金属矿床成矿物质来源:原位S-Pb同位素证据
Source of Ore-forming Materials of the Tongshanling Cu-polymetallic Deposit in Hunan Province:Evidence from in situ S-Pb Isotopes
摘要
Abstract
The Tongshanling Cu-polymetallic skarn deposit is located in the western part of the Qin-Hang metallogenic belt,with orebodies mainly occurring along the contact zones between granodiorite and carbonate rocks.The mineralization process can be divided into four stages,involving stageⅠgarnet-pyroxene,stageⅡactinolite-epidote-chlorite,stageⅢ quartz-polymetallic sulfides,and stage Ⅳ quartz-calcite.The ore minerals consist mainly of chalcopyrite,galena,sphalerite and pyrite,with minor pyrrhotite,arsenopyrite,etc.The in-situ δ34 S values of sulfides range from 2.8‰ to 7.0‰,indicating that sulfur is principally derived from magma,with few involvement of strata sulfur.The in-situ lead isotope composition of sulfides(206 Pb/204 Pb=18.728～18.741,207 Pb/204 Pb=15.742～15.762,208 Pb/204 Pb=39.006～39.070)is consistent with that of granodiorite,revealing a predominantly magmatic origin for lead.关键词
