阿尔泰山南缘克朗盆地泥盆纪火山沉积与矿产

Devonian volcano-sediments and mineralization of Kelang basin in southern Altay mountains

摘要: 新疆阿尔泰山南缘克朗晚古生代火山-沉积盆地盆地,位于西伯利亚板块南缘泥盆纪陆缘裂谷带中,在早泥盆世发生了大规模多期次的火山活动,在康布铁堡组火山沉积地层中形成了恰夏、铁木尔特和阿巴宫多个VMS型铜铅锌铁多金属矿床;中泥盆世火山作用减弱,在阿勒泰镇组沉积地层中形成SEDEX型红墩铅锌矿床。

Abstract: The Kelang basin of southern Altay mountains is located in rift of the Devonian contiental margin of Sibelia plate. In Early Devonian, a large volcanic activity occurred many times and many VMS-type Cu, Pb, Zn and Fe mineralizations were formed in the Kelang basin (Kangbutiebu Formation); Few volcanic rocks were developed and a SEDEX-type Pb-Zn deposit was formed in Middle Devonian (Altay town Formation).
