川北地区铀成矿特征与成矿预测

Uranium Mineralizaton Feature and Metallization Prognostication in North Sichuan

川北地区是我国南方重要的砂岩型铀矿成矿带之一。文章通过区域地质背景和典型铀矿床研究,总结了该区的铀成矿规律,厘定了砂岩型铀矿区域预测要素。根据预测要素构置了区域预测变量,并应用特征分析法圈定18片预测区,为今后的总体找矿部署提供科学依据。

North Sichuan is one of the important metallogenic region of sandstone- hosted uranium de- posits in south China. Base on the study of the regional geologic setting and typical deposits, we summa- rized the regional metallogenic rules and predictive factors in this paper. According to the predictive fac- tors we constructed predictive variables and delineated 18 forecasting areas by characteristic analysis, which provides a scientific basis for the general deploy of geological prospecting work of sandstone - hos- ted uranium deposits.
