摘要
本文研究了西昆仑造山带南带的新疆赛力格塔什刚玉矿床，该矿床赋存于古老基底的变质 岩系中，含矿岩石为眼球状黑云母长石片麻岩，眼球部分由刚玉（中心）及钾长石（外围）组成，基体为 黑云母及钾长石。经岩石化学及微量元素等的研究表明，这是一个由贫硅富铝的沉积岩经高级变质 作用形成的矿床。
The corundum deposit studied in this paper was occurred in fundamental metamorphic rock series in the north part of Western Kunlun orogenic belt. The corundum-bearing ore is a kind of ocular biotite-feldspar gneiss, the part of 'eyeball' is composed of corundum(centre) and K-feldspars(outside lane) and the ground mass is composed of biotite and K-feldspar. Based on the investigation by petrochemistry and trace elements, It is regarded that this corundum deposit are formed by metamorphism from the sedimentary rocks riched in aluminium.
