Located in the Qimantag metallogenic subzone and monoblock exploration area, the Hutouya polymetallic ore field belongs to the west segment of East Kunlun Mountains. Based on field investigation of structures and multiple-information analysis as well as previous research results obtained in the ore field, the authors summarized main characteristics of ore-controlling structures, discussed the ore-forming geological conditions from the angle of ore field structure, and analyzed the influence of the nearly EW-, NE- and NWW-trending fractures on the ore belt. The difference between structures of various orders was analyzed in the aspect of their roles in mineralization. Some conclusions have been reached based on a comprehensive analysis: (1) Nearly EW, NE- and NWW-striking fractures constitute the main ore-controlling structure and control the spatial distribution of the ore. deposits; (2) Nearly EW-, NE- and NWW-striking secondary fractures and intrusive contacts belong to the metallogenic epoch and control the distribution of Fe-Cu polymetallic ore bodies; (3) Ore bodies were reformed by NE- and nearly SN-striking fractures; (4) Since the Indosinian period,there have been skarnization mineralization stage and hydrothermal reformation stage related to fault-fractures; (5) As for ore- searching directions, the intrusive contact structure, the nearly EW- trending faulted structures, the intersections of faults and the contact areas between different lithological characters are favorable metallogenic areas.

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. © (2014) Trans Tech Publications, Switzerland.
