多源遥感信息在喀喇昆仑火烧云一带找矿预测中的应用
Application of Multi-Source Remote Sensing Information to Metallogenic Prediction in the Huoshaoyun Region of Karakorum, Xinjiang
摘要
Abstract
Prospecting of lead-zinc deposits was conducted based on the ASTER and Worldview-2 remote sensing data in the Sachakou-Hu-oshaoyun area, Karakorum in Xinjiang. The spectral characteristics of different rocks and ore bodies were analyzed for typical deposits. Spectral analysis of limestone showed two absorption peaks, of which the intense peak is CO32- absorption whereas the weak peak is Al-OH absorption. The spectral curves of lead-zinc mineralization rocks were characterized by CO32-, Al-OH and Fe3+ absorptions. The remote sensing anomalies including calcite, Al-OH, ferrous and ferric iron were extracted from ASTER data. These remote sensing anomalies were distributed in NE-trending belts, consistent with the pattern of known geologic bodies in this area. Based on real data, the exploration model of lead-zinc deposits was established by using the alteration anomalies and geology characteristics in this area. And then, the alteration anomalies from remote sensing data were selected combined with regional geo-logical conditions. Using the analogy comparison theory, five prospecting target areas including Sachaokou, Maanshan, Niulangshan, Jinyushan and Wait-oushan were delineated. This work indicates that using multi-source remote sensing information can help promote the lead-zinc ore prospecting in the alpine landscape areas of Karakorum.关键词
