Abstract:

The study area is located in the Indosinian Bokalike-Xiangride gold,lead,zinc,iron and graphite metal-logenic belt.The geological,geochemical and geophysical characteristics of the region have been studied.The results show that the gold ores are mostly found in the late Indosinian Triassic gray fine-grained granodiorite in the study area,and a few are found in the pyrite fossil veins.The NW fault structure is the ore-conducting structure and ore-controlling structure in the study area.Gold mineralization is closely related with pyritization and silicification.The geochemical measurements of 1∶50 000 and 1∶25 000 all delineated the comprehensive anomalies dominated by Au,and the Au and associated elements were all pided into three concentration zones,which were good geochemical prospecting indicators in the study area.The delineated blue magnetic anomaly DC-2008-M247,with large scale,high amplitude and high intensity,is an important geophysical prospecting indicator in the study area.It has been proved that two new gold mineralization zones and 11 gold (mineralization) orebodies have been found in the study area,and the mineralization zone has been extended and stabilized,indicating that the study area has good ore-prospecting potential in both shallow and deep areas.
