A STUDY ON THE CORUNDUM DEPOSIT IN SAILIGETASHI, XINJIANG |
| |
Abstract: | 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. |
