摘要

在分析了沽源地区铀矿床成矿地质特征的基础上, 总结了区域铀矿找矿标志, 提取了各类找矿信息, 利用GIS的空间分析功能分别提取了地层、构造、潜火山岩、热液蚀变、化探异常、航磁异常、航放异常等14个有利分析因子, 建立了层次分析模型, 并根据该区成矿概率的分布进行了成矿远景区的预测, 圈定Ⅰ级远景区2个、Ⅱ级远景区7个、Ⅲ级远景区5个, 为在沽源地区开展进一步铀矿找矿奠定了基础。

Abstract

Based on the analysis of metallogenetic characteristics of the uranium deposits in Guyuan region, summarizes the regional prospecting symbol, Various geological anomalous information of the area is analyzed. With the spatial analysis function of GIS, extracte the 14 favorable factors include strata, structure, subvolcanic rock, hydrothermal, alteration, geochemical anomaly, aeromagnetic anomalies, etc. were extracted, and the analytic hierarchy process model was built. Finally, based on the analysis, favorable areas were predicted according to the ore formation probability values.The prediction showed two firstgrade metallogenetic targets, seven secondarygrade metallogenetic targets and five threegrade metallogenetic targets, which laid the foundation for further prospecting in Guyuan region.

Key words： Analytic hierarchy process; Uranium minerogenetic prediction; Guyuan region; GIS.
