Remote Sensing Study of Metallogenic Condition in West Kunlun Laobing-Zankan Ore Concentration Area

This paper summarized remote sensing technology method suitable for the iron ore of sedimentary metamorphic type in arctic-alpine high altitude localities through mineralized alteration information extraction of remote sensing from Aster image and remote sensing interpretation from Worldview-Ⅱ image. Based on the background analysis of iron ore mineralization in the ore concentration area, and in view of Aster and Worldview-Ⅱimage features and major types of iron ore mineralization, the technology and method for mineralized alteration information extraction of remote sensing mainly focusing on iron stained anomaly is put forward. Meanwhile, its reliability is analyzed. The author made full use of the advantages of the high-resolution images from Worldview-Ⅱ and interpreted the metallogenesis including lithology, structure, intrusive rock, particularly the ore body and mineralized zone, which are much clearer than previous images. Prospecting model of iron ore remote sensing is set up through remote sensing analysis of ore-controlling conditions. Four iron ore mineralization belts except the known iron ore deposit are delineated. The comparison analysis is reliable between part of the field confirmation and the known mineral deposit. It is concluded that Laobing-Zankan ore concentration area boasts good prospecting potential through the remote sensing study of iron ore minerogenetic condition in the Laobing-Zankan ore concentration area.
