Morpas证据权重法在遵化滦南地区成矿预测中的应用

Application of Evidence Weight Method Basing on Morpas to Metallogenic Prediction in Zunhua to Luannan area

本文通过对遵化滦南地区区域地质背景及成矿要素分析,综合地、物等多元地质找矿信息,结合Morpas对研究区铁成矿信息定量提取,将研究区划分为2500m×2500m的网格单元共1353个,利用证据权模型预测,圈定铁成矿远景区4个,实现对研究区铁矿的成矿预测。

By the metallogenic geological conditions and factors analysis in Zunhuan to Luannan area, we make an integrated use of the physical, geology and other geological prospecting information. At same time, Combining with Morpas, we quantitative extract metallogenic information, and divide into 1353 units with a range of 2500km×2500m for each unit. By using weights of evidence model to predict, we circle 4 metallogenic prospect areas and realize metallogenic prognosis of regional iron ore.
