Delineation of iron formation in Wenquangou Group along Heiqia Pass in West Kunlun metallogenic belt
摘要
Abstract
Using middle and high resolution remote sensing data such as WorldView2, IKONOS, QuickBird, ASTER and ETM+, and their processing methods such as de-relatedcalculation, ratio calculation, principal component analysis and image fusion, the authors delineated a siderite-hematite mineralization belt along Heiqia Pass in West Kunlun metallogenic belt on the basis of the field survey.The belt occurs in the Lower Silurian Wenquangou Group and stretches 120 km long northwestward, and has been eroded by the rock mass in the northwest part and truncated by Kalatage fault in the southeast part.Its ore-bearing layers remain stable, and its continuity in formation strike and dip direction is very good, so the belt is favorable for mineral resources investigation.The results of the survey show that geological survey with remote sensing technology is one of indispensable methods in regional geological and mineral resources survey, and will play an important role in the geological prospecting in western metallogenic belts, especially in the complex and dangerous regions.关键词
