摘要
哈密市土屋铜矿床是新疆东天山地区发现的大型斑岩型铜矿床，该矿床产于石炭纪闪长玢岩和斜长花岗斑岩中，位于大草潍断裂和康古尔塔格断裂之间的下石炭统企鹅山群的火山熔岩与碎屑岩、火山碎屑岩的接触带上。近矿围岩蚀变主要为强硅化带、黑云母带、石英一绢云母带、绢云母一青磐岩化带和青磐岩化带。主要成矿过程发生在120℃～350℃之间，矿石δ^34S=0．2‰～8．0‰。硫来自地球深部。文章较为详细地分析研究了土屋铜矿床地质特征，对于确定矿床类型、成因及成矿预测有一定的借鉴意义。
Tuwu -Yandong copper deposit in Hami, eastern Tianshan is a large porphyry copper deposit, and located in carboniferous diorite - porphyries and plagioelase granite - porphyry. The deposit lies in contacting zones among late carboniferous Qieshan group lava, elastic rocks and volcanic - clastic rocks between Dacaotan and Kangguertage faults. Wallrock alterations near ores are mainly silicification belt, biotitic belt, quartz - aericite belt, sericite - propylitization belt and propylitization belt. Ore mineralization occurred at temperature of 120℃ - 350℃ withδ^34 S of 0.2‰-8.0‰. Baeed on geology characters of Tuwu - Yandong copper deposit, the deposit type is defined.
