Discussion on genetic correlation between Huashan granite body and Guposhan granite body based on comparative analysis of fault structure features in remote sensing image

Abstract

Huashan granite body and Guposhan granite body are two neighboring granite bodies in Guidong area of Guangxi. They are closely related to the polymetallic mineralization of the area. The study of their formation is of practical significance for expanding prospecting for the non- ferrous metal mineral resources in Guidong area. As the fault structure was genetically closely related to the igneous geological action of the granite body,the authors investigated their spatial contact characteristics so as to help the discussion of the genetic correlation between the granite bodies. Using the ETM+remote sensing image as the source of information and based on extracting the linear structure information in four directions,i. e.,SN,EW,NE and NW,from the remote sensing images of Huashan and Guposhan granite bodies,the authors carried out the comparative statistical analysis,comparative rose diagram analysis and comparative equi- density map analysis as well as comparative structural stress field analysis of the fractures through trend surface simulation of the remote sensing linear structure in the two rock bodies.Finally,the genetic relevance and difference between the two rock bodies were detected through the comprehensive analysis.
