A NEW TYPE OF GOLD DEPOSIT RELATED WITH THE RUPTURE-METAMORPHISM: THE SAREKUOBU GOLD DEPOSIT IN THE ALETIA CITY,XINJIANG

YIN,yi-qiu~1,LI Jia-xing~2 (1.Guilin Research lnstitute of Geology for Mineral Resources,Guilin, Guangxi 541004 China; 2.No.706 Geological Party,XinJiang Nonferrous Metal Geoexploration Bureau,Aletia, Xinjiang 836500,China)  
The wallrock alteration of the Sarekuobu gold deposit shows the linear progressive metamorphism.There are more biotite and amphibole near the ore body,and there are also the sillmanite and andalusite etc.,which are the metamorphic minerals formed at high temperature of the low-pressure facies series.Contemporarily there are biotite,amphibole,garnet,epidote,actinolite,tremolite,siderite etc.,which are the metamorphic minerals formed from special origin,in the gold-bearing quartzite.Moreover, the tough shear deformation of the gold-bearing quartzite was very weak.Therefore,these geological features are obviously diffierent from the gold deposit of the structural alteration rock type or the shear zone type.It may be a new type of gold deposit.It was formed by the fractural metamorphism.
