Genesis and Prospecting Criteria of Zixi Gold Deposit in Xuefeng Arc Structure Belt of Hunan Province
[Purposes]Zixi gold deposit is a newly discovered gold deposit in Xuefeng arc structure belt,Hunan province,which occurs in the altered dikes in recent years.[Methods]By summarizing the previ-ous research results,and combing the field geological characteristics and rock geochemical characteris-tics,the deposit genesis is discussed and the prospecting criteria are summarized.[Findings]The results show that the intermediate-basic magmatic rocks in the area are mainly gabbro-diorite,which is closely related to the tectonic environment of intraplate continental rift and belongs to the product of post-collision extension.The deposit was formed in the intracontinental orogenic process of the Xuefeng Mountain,and the ore-forming materials may be mainly derived from the metamorphic basement.Fault structure,basic dike and arsenopyrite hydrothermal alteration are important marks for prospecting this type of gold deposit.[Conclusions]The research results can provide reference for the search of the same type of gold deposits in the region.
