【 摘 要 】

Wenquangou Group ore-bearing belt from Muji, Bulunkou, Tashikuergan to Heiqia is an important metallogenic belt of Western Kunlun area. Heiqia iron polymetallic metallogenic belt is located in its southeast section, having a good prospecting prospects. In this paper,high resolution remote sensing interpretation and mineralization anomaly information enhancement and extraction technology were used to delineation of Heiqiairon polymetallic mineralization zone in West Kunlun region. With the right amount of field sampling and verification test, we established remote sensing geology prospecting model, which will provide the basis for future remote sensing metallogenic belt in West Kunlun to find similar minerals. Survey results show that a copper-lead-zinc polymetallic mineralization with iron was found in Heiqia area. Survey results show that a copper-lead-zinc polymetallic mineralization with iron was found in Heiqia area. A great potential for prospecting siderite - copper zinc hematite mineralization belt was found, which extends in a length of about 60 kilometres, with width of 200 ∼ 500 m, including a plurality of mineralized bodies. The mineralized bodies are located in the transition site that clastic rock to carbonate rock of the D segment in the Wenquangou Group, appearing in bedded, near bedded and lenticular. The occurrence of the mineralized bodies is generally 40° ∼50° ∠68° ∼81°, in accordance to the strata. The length of single body changes from several tens meters to hundred meters, the exposed thickness on the surface changes from ten centimetres to several meters. The surface ore minerals are mainly hematite and limonite, with a small amount of hematite and siderite. The Pb-Zn- Cu mineralization is commonly found in the carbonate rocks in the upper part of the iron ore body, which is also found in the upper part of the iron ore body. It is concluded that the type of deposit is Submarine sedimentary- Metamorphism-Hydrothermal modification.
