According to Re-Os isotopic isochron age(506±14 Ma)for molybdenite in Duobaoshan and Tongshan copper(molybdenum)deposit,as well as the regional geological data,it is considered that the emplacement age of Duobaoshan granodiorite is in pre-Ordovician.
6Ma,据多宝山、铜山铜(钼)矿床中辉钼矿的Re-Os同位素等时线年龄(506±14Ma),结合区域地质资料,认为多宝山花岗闪长岩侵位年龄为前奥陶纪,被多宝山花岗闪长岩岩体侵位的矿区地层时代、多宝山铜矿成矿主期、与成矿有关的多宝山北西向控矿、容矿构造应属于前奥陶纪,且多宝山花岗闪长岩形成于火山岛弧或活动的陆缘构造环境,岩浆来源以幔源物质为主,同熔了部份壳源物质。
