Metallogenic Characteristics and Prospecting of the Iron Mine in Altay and North Junggar Area

According to the prospecting practice and statistics of iron mineralized area in Altay and north Junggar area, and based upon the comprehensive study on iron formation, alteration, main geological bodies, mineralization, ore forming geological conditions, regional minerals, geochemical anomalies and aeromagnetic anomalies, space combination, the iron ores in this area were divided into 7 types, which are magmatic type, hydrothermal type, skarn (metasomatism modified) type, marine volcanic eruption and deposition (modified) type, marine fumaroles and hydrothermal (metasomatism modified) type, continental sedimentary type, marine sedimentary type (ancient placer deposit), residual type (modern placer deposit). Prospecting signs for major types of iron ores in region exploration were also summed up. The deployment idea is to deepen old district and develop new searching areas, the marine volcanic eruption and deposition(modified) as well as marine fumaroles and hydrothermal (metasomatism modified) magnetite type iron ores were main direction for exploration. Major attention should be paid to the southern Altay Abagong and Maize old mining orefield, bedrock area of low working degree and some aeromagnetic anomaly zones of shallow cover area in southern Altay region and northeastern margin of the Junggar.
