Geological Characteristics and Geophysical Prospecting Signs of Gold Mine in Pengboshan area, Inner Mongolia
-
Abstract
Pengboshan area belongs to eastern Beishan metallogenic belt, and located in the west of Ejina area, Inner Mongoulia. The Carboniferous Lvtiaoshan and Baishan Formation are primary ore layers, the type of gold mineralization is quartz vein, whose production is controlled by fault structures. Induced polarization intermediate gradien survey was carried out in No.1 and No.2 testing area, and many large-scale high resistivity anomaly belts have been detected, which indicates the existence of concealed quartz veins. Apparent resistivity of 600 to 1200Ω.m is the geophysical prospecting symbol for finding those concealed quartz veins. Most of the anomaly belts don't have obvious abnormal apparent chargeability, thus the anomaly is reflected as barren or weak mineralized quartz vein. However, high apparent polarization is found in No.1 testing area, with the characteristic of high resistivity and high polarizability. Therefore, we predict that the concealed quartz vein may contain considerable metal sulfides, and could have preferable potential in further prospecting work. -
