Granite In Northern Guangxi Geochemical Characteristics And Metallogenic Potential Analysis

The northern Guangxi area,Guangxi,belongs to the western and western section of the contact zone between the Yangtze River and the Yangtze River.The granites in the area are developed in the region.The representative rocks are the cat Hill granite,the ocean mountain granite,the Dubang granite and the Yuanbaoshan granite.Based on the regional geological survey of the granitic bases in northern Guangxi,the geochemical characteristics of the granitic bases are studied and the corresponding geological geochemical models are established on the basis of the regional geological survey of the granitic bases in northern Guangxi.The metallogenic potential in the area is explored by using the microscopic characteristics of the size,characteristic ratio and distribution curve of the inter component correlation and the distribution characteristics of the known minerals in the region.It is of great theoretical significance to further understand the geochemical characteristics of granites in northern Guangxi and further explore their evolution rules and geological background.The basic results are as follows:(1)Granite diagenesis ages in the study area mainly include four fort,Caledonian,Indosinian and Yanshan.(2)According to the stratigraphic age from the old to the new,Yuanbaoshan-Baoshan-Du pound-Cat Mountain,the variation of the constant elements presents a certain rule,but the variation laws of the main elements are different.(3)the four subregions in the study area have certain similarities in the initial abundance value and element combination of trace elements.The four elements of W,Sn,Bi and Pb all showed strong enrichment state,and the element content was far higher than the Clark value of the crust element abundance;Cu,Ni,Mo,Ti,Co,Au and other elements were seriously poor,and the content was far below the Clark value of the elemental abundance of the earth's crust,which was in accordance with the whole background of the whole north of Guangxi and Southern China.But their distribution patterns are different in each sub region.(4)In large-scale magmatic activities,there are differences in the mineralization potential around the granitic granites in northern Guangxi.
