Abstract
Dachang ore field is located in the central of Au, Sb, Hg metallogenic belt in the north Bayankela mountain, with the Maduo - Gande deep major fault as its regional guide mineral structure. The gold deposits have grew up in the fracture - fissure system of large share zone in BaYanKaLa mountain group of Triassic strata, and Magmatic activities in Yanshan Period provides favorable conditions for the activation, migration, enrichment and mineralization of gold element. Geophysical - geochemical anomaly and remote sensing of this area have shown that they are related with the mineralization, that means abnormal area with bigger Intensity is often located in the cross area of tectonic alteration and mineralization. Triassic strata, the north - west fault and its secondary structure - rock system and geophysical - geochemical anomaly are the obvious symbols of gold prospecting in the area. Through the metallogenic regularity, obvious symbols and distincting some geophysical - geochemical anomalies, more large and medium-sized gold deposits have been found. We should along the Maduo - Gande fault zone, extending for east - west trend and the depth, and larger scale gold deposits is expected to be found.
