中文摘要：

阿希金矿是西天山地区典型的低硫型浅成低温热液型金矿床，发育了以矿体为中心，向外依次为硅化、黄铁绢英岩化和青磐岩化的蚀变分带。对矿区火山岩和蚀变岩型矿石的主量、微量元素进行了测试，并借助Isocon法对黄铁绢英岩化、硅化和石英-碳酸盐化进行了元素质量迁移定量计算。结果表明：黄铁绢英岩化岩石富集SiO2、K2O、Ag、As、Mo、Bi和Pb，亏损CaO、Na2O、Sr、Cs和Ba；硅化过程中富集SiO2、Bi、Pb、Ag和As，而MgO、CaO、Na2O、Ba和U出现亏损；石英-碳酸盐化过程中元素迁移量较大，主要富集SiO2、MgO、CaO、Li、Ba和As，亏损K2O、Na2O、P2O5、Pb和Zn等元素。结合蚀变岩石显微特征，认为热液蚀变过程中的元素迁移与矿物的蚀变或生成直接相关，而且含Au络合物在Au成矿中扮演重要角色。

英文摘要：

The Axi low-sulfidation epithermal gold deposit, located in the western Tianshan, develops a clear alteration holo, which shows changing outward from quartz veins of the main orebodies, through a zone of silicification to a phyllic alteration zone, followed by the propylitization. This paper systematically analyzes the major elements and trace elements of the volcanic rock and altered rock of the Axi gold deposit. On this basis, the element mobility in pyritic-phyllic alteration, silicification and quartz-carbonatization is calculated quantitatively by using the isocon method. The results show that the pyritic-phyllic alteration is enriched inSiO2,K2O,Ag,As,Mo,Bi and Pb, and depleted in CaO,Na2O,Sr,Cs and Ba. During the processes of silicification, SiO2 ,Bi,Pb,Ag and As are added, meanwhile MgO,CaO,NaEO,Ba and U are obviously brought out. During quartz-carbonatization, the tremendous migration of clemens was observed, showing that the altered rock increased SiO2 ,MgO,CaO,Li,Ba and As, countrary with K2O,Na2O,P2O5, Pb and Zn. Combining with the microcharacetistics of altered rock, the element migration in hydrothermal alteration is directly associated with the mineral changes, and the gold complex compounds play a significant role in mineralization.
