吉林省夹皮沟—海沟成矿带金矿定位时代

Location time of gold deposits in Jiapigou Haigoumineralization zone, Jilin Province

夹皮沟－海沟金矿带是华北板块北缘东段构造—岩浆活动带，金矿床定位于大型区域性构造交汇或转折部位，金矿体定位于中生代时期叠加在早期构造之上的脆性构造及中生代时期产生的脆性构造中；金矿体容矿岩石多种多样，容矿岩石形成时代不一；含矿石英脉的氩－氩年龄约为１０２Ｍａ。所有研究表明，夹皮沟－海沟金矿成矿带金矿定位时代为中生代。

JiapigouHaigou gold mineralization zone is a structuralmagma active zone in eastern part of the northern margin of North China plate. The gold deposits were located in the turn or intersecting of large regional structures, gold ore bodies were located in brittle structures, occurred in the early stage structures or formed in Mesozoic era. Wall rocks of gold ore bodies formed in different era are diversified. The ArgonArgon age of goldbearing quartz vein is approximately 102 Ma. All of the above studies show that the location era of JiapigouHaigou gold mineralization zone is Mesozoic
