Ore-controlling structure analysis and prospecting instruction of Xuefeng gold field in southern section of Jiangnan Orogenic Belt

Xuefeng gold field, located at the southern section of Jiangnan Orogenic belt, including Chanziping, Daping, Hengbidong gold deposits. It is of great significance to study the ore-controlling structure characteristics and ore-controlling rules in Xuefeng gold field for the study of the southern section of Jiangnan Orogenic belt and the deep peripheral prospecting. By analyzing and studying the metallogenic geological background, ore-body characteristics and ore-controlling structural characteristics of Chanziping and Daping gold deposit, combined with the previous published data, the study summarizes the ore-controlling structural characteristics of the gold deposit and its relationship with gold mineralization, and tries to estimate the stress system and deformation process in the metallogenic period. According to the study, the NE schistoscopic zone in the ore field is the ore guide structure, and the NW schistoscopic zone is the associated structure of the NE fault, which often develops in or near the NE schistoscopic zone, and is the main ore-bearing geological body of the gold deposits in the area..In the late Indosinian period, the principal stress of Xuefeng gold field is in the NW-SE direction. Based on the structure, vein characteristics, it is considered that a good prospecting space is located in the deep of Xuefeng gold field.
