| 摘 要： | 北山黑山岭位于塔里木板块北部北山裂谷带内.该带侵入岩较为发育,主要为华力西构造岩浆带产物.通过对区内基性岩体同位素测定,获得岩体锆石SHRIMP U-Pb年龄为(404±3)Ma,(375±3)Ma和(280±2)Ma.认为基性岩与裂谷玄武岩和洋中脊玄武岩具同源性质,证实其形成于拉张构造环境.提出该带具岩浆熔离型铜镍矿成矿可能.

| 关 键 词： | 北山 SHRIMP测年 基性-超基性岩 岩浆熔离型铜镍矿床 |

| Abstract: | Beishan Heishanling is located in the Beishan rift zone in northern Tarim plate,where the intrusive rock is widely developed.It is the result of the Variscian tectonomagmatic belt.The isotope chronology of basic body is first studied in this region.Zircon SHRIMP U-Pb age of the body is 404±3Ma,375±3Ma and 280±2Ma.And the basic body is cognate with the raft basalt and median ridge basalt;it is proved that it formed in the tensional structural environment.Minerotect of magma liquation-coppernickel mine is probability in this region. |
