新疆塔什库尔干地区矿产资源丰富,但环境恶劣地形复杂其地质勘查工作程度不深,传统地质找矿方法难以展开。针对此问题,该文通过多光谱 ASTER 遥感卫星影像数据,对其进行最大值、最小值、均值、标准差以及协方差等统计分析,探索选取矿化蚀变异常信息提取各波段波谱特征,在遥感矿化蚀变异常信息提取机理研究和已有地质资料分析基础上应用主成分分析法,辅助研究区矿物蚀变指数(波段比值、运算)和掩膜处理模型,提取出该区域的矿化蚀变异常信息。该研究方法的实现为地质环境恶劣、传统找矿难以展开的地区进行成矿预测与资源评价提供科学有效的解决途径。
新疆塔什庫爾榦地區礦產資源豐富,但環境噁劣地形複雜其地質勘查工作程度不深,傳統地質找礦方法難以展開。針對此問題,該文通過多光譜 ASTER 遙感衛星影像數據,對其進行最大值、最小值、均值、標準差以及協方差等統計分析,探索選取礦化蝕變異常信息提取各波段波譜特徵,在遙感礦化蝕變異常信息提取機理研究和已有地質資料分析基礎上應用主成分分析法,輔助研究區礦物蝕變指數(波段比值、運算)和掩膜處理模型,提取齣該區域的礦化蝕變異常信息。該研究方法的實現為地質環境噁劣、傳統找礦難以展開的地區進行成礦預測與資源評價提供科學有效的解決途徑。

It is a mineral-rich area in Taxkorgan of Xinjiang that traditional prospecting method for mine is difficult to start with,and geological exploration is still inadequate because of the severe environment and complex terrain.The statistical analysis is given for maximum,minimum,mean,standard deviation and covariance based on multi-spectral data of ASTER remote sensing image,and each band spectrum character is probed into choosing the mineralizing alteration abnormal information.The PCA method based on the mechanism of mineralizing alteration information and the analytical geological structure has been applied in the study area,in which mineralizing alteration information are put forward with the support of mineral alteration index(band ratio,arithmetic)and masking processing model in the research area.It could provide a scientific solution for mineral resource prediction and assessment about serious geologic environment and difficult field without traditional prospecting method.
