地球化学信息挖掘在云南易门铜矿区找矿预测中的应用
Prospecting Prediction by Geochemical Information Mining in Yimen Copper Area, Yunnan
摘要
Abstract
Taking Yunnan Yimen copper ore district and its peripheral as the study area, 12 microelements in different ages strata, geochemical distribution characteristics of microelements in stream sediments, and the relation between geochemical indicators and metallogenesis are analyzed. Based on the geochemical mining theory , the principal component factor of microelements with Pan-Kriging model and three-dimensional visualization analysis of geochemical anomalies, GIS-based multi-information forecasts and other methods are used. The study area based on the GIS comprehensive geochemical prospecting model is established. Geochemical anomaly weak information enhancement and composite indicator based on geochemical metallogenic prediction are carried out. Both prospective areas of 9 exploration and 17 prospecting targets are delineated with good exploration results.关键词
