探讨新疆哈密土屋斑岩型铜矿成矿特征及成因类型

Metallogenic characteristics and genesis of porphyry copper mine Tuwu types in Xinjiang Hami

土屋斑岩铜矿位于吐鲁番-哈密古陆块南部边缘泥盆纪岛弧带上,系其北部东准噶尔洋(卡拉麦里洋)向南俯冲的产物。斜长花岗岩以及石炭纪闪长玢岩体是该矿的主要富矿位置。矿化特征非常均匀,呈现细脉侵染状特点,并且围岩蚀变特征具有明显的分带性,矿化体在厚度上非常大,品位不高,组分简单。在新疆地质研究工作的基础上发现了哈密土屋斑岩型铜矿,它的发现为区域内寻找此类矿床提供了有利参考,并且,还能进一步促进新疆地区的矿业发展,意义重大。

The Tuwu porphyry copper deposit is located in the Turpan - Hanai block in southern edge of Devonian island arc belt, the North East Junggar ocean （Cara Liyang） southward subduction of the product. The ore body mainly occurs in the Carboniferous diorite and plagiogranite porphyry rock body. It is a kind of fine vein disseminated mineralization, which has the characteristics of large thickness, uniform mineralization, low grade, simple composition and obvious alteration zoning. The discovery of this deposit not only has important guiding significance for the geological prospecting of Xinjiang porphyry copper deposit, but also plays an important role in promoting the development of mining industry in Xinjiang in the future.
