中文摘要: 大通沟位于青藏高原北缘的秦祁昆中央造山系阿尔金构造带(Ⅱ)和柴达木-西秦岭微地块,柴达木地块与阿尔金构造带交界处,广泛分布了元古代碳酸盐岩—碎屑岩中深变质岩系建造,构造和岩浆活动强烈,主要侵入岩有闪长岩、花岗闪长岩及少量二长花岗岩。分析了分布较广的闪长岩中锆石U-Pb年龄为367.5±5.2Ma,属晚泥盆—早石炭世;锆石中Th/U比值在0.28~0.94之间,平均0.58,具典型岩浆锆石特征;岩体类型属钾质钙碱系列,具较强的轻稀土富集而重稀土相对亏损的配分模式,岩体侵位与海西期印度板块和欧亚板块俯冲-碰撞的构造作用诱发的阿尔金走滑断裂活动有关。
Abstract:The Datonggou area is located in the Altun tectonic belt (II) on the northern margin of the Qinghai-Tibet Plateau , at the junction of the Qinling-Qilian-Kunlun central orogenic system and the Qaidam-WestQinling massifs. The middle-high metamorphic carbonate rock-clastic rock of Proterozoic was widely distributed in the area. There are strong tectonic and magmatic activities in the area. The intrusive rocks are mainly diorite, granodiorite and a small amount of monzoniticgranite.In this paper, the zircon U-Pb age of the widely distributed diorite is 367.5±5.2Ma, which belongs to the late Devonian-Early Carboniferous.The ratio of Th/U in zircon is between 0.28 and 0.94 with an average of 0.58, which is characteristic of typical magmatic zircon.The rock body type is a potassium calc-alkaline series, which has a A distribution model with rich in light REE and loss in heavy REE.The pluton emplacement is related to The Altun strike-slip fault induced by the subduction and collision orogeny of the Indian plates and the Eurasian plates in Hercynian, therefore there is an excellent exploration prospect in this area.
