| 摘 要： | 北武夷山地区高家山矽卡岩型铜钼多金属矿床位于扬子地块与华夏地块碰撞对接带萍乡-广丰深大断裂的甫侧,前人获得与成矿有关正长斑岩、花岗斑岩体的K-Ar法同位素年龄为63.6 Ma、84.7 Ma.本文对与成矿有关的正长斑岩和侵入于正长斑岩、花岗斑岩中的闪长玢岩分别进行了精确的锆石U-Pb定年研究,获得锆石206Pb/238U年龄分别为232.7±0.6 Ma和219.6±1.5 Ma,属印支期.通过分析矿石的氧、硫同位素和成矿岩体的地质地球化学特点,认为高家山铜钼矿床与印支期富碱性岩浆活动存在密切的时空和成因联系.因此,成矿岩体年龄间接地反映了本矿床的形成时代为印支期,提供了北武夷山地区印支期成矿作用的新信息.

| Abstract: | Gaojiashan copper and molybdenum deposits in the northern Wuyi Shan region,Jiangxi province,is tectonically located on the southern margin of the Pingxiang-Gangfeng fault belt,the collisional suture between Yantze plateform to the north and Huaxia plateform to the south.The K-Ar dating ages by previous studies for orthophyre and granite porphyry related to mineralization are 63.6 Ma and 84.7 Ma,respectively.Precise zircon U-Pb dating was carried out on the orthophyre,and diorite porphyry intruding orthophyr... |
