Landsat 8 OLI遥感数据在鹿井矿田铀多金属矿化蚀变信息提取中的应用
Application of Landsat 8 OLI Data in the Extraction of Alteration Information for Uranium Polymetallic Mineralization in Lujing Field
摘要
Abstract
Lujing ore field is located in the southwestern section of Taoshan-zhuguang uranium metallogenic belt,and an important granite-type uranium metallogenic prospect area in China with eleven uranium deposits.Copper-tungsten-molybdenum polymetallic deposits were produced in northwest side of the ore field.Due to the long time term exploration and mining,the reserve are facing exhausting,but the next prospecting direction is not clear.The anomaly information of iron-stained and hydroxyl alteration are believed is related to uranium polymetallic mineralization.This paper extracted the alteration by principal component analysis and density segmentation method with Landsat 8 OLI data.The result shows that the anomaly information of iron-stained and hydroxyl alteration are abundant in the ore field and strong alteration anomaly is distributed in uranium polymetallic deposit.Intensity of alteration anomaly is positively correlated with mineralization information.The extracted alteration anomaly distributing in Indosinian granite spread northeast ward,which is obviously controlled by the NE main fracture.The alteration anomaly distributing in Cambrian strata spread northwest ward,which is obviously controlled by the interlayer fracture zones.One prospect for copper-tungsten-molybdenum polymetallic prospecting and five prospects for uranium prospecting were prognosticated based on the information of iron-stained,hydroxyl alteration in the Lujing ore field,which provides a new direction for further exploration.关键词
