| 摘 要： | 通过研究鄂西地区典型沉积型磷矿矿床成矿特征,总结其成矿规律,选取含磷岩系下震旦统陡山沱组含磷岩系的分布、岩相古地理、古构造、岩石组合、陡山沱组地层厚度、南沱组冰碛砾岩厚度作为预测要素变量;运用秩相关系数法分析各预测要素,确定矿床的定位预测要素的重要变量区间。最终基于MRAS软件,通过特征分析法对预测要素进行分析,确定了34个A类预测区。

| Abstract: | Through the study of western Hubei province typical sedimentary phosphorite deposit metallogenic characteristics, summarizes the metallogenic regularities, checkes phosphoric strata distribution of the lower Sinian Doushantuo, lithofacies palaeogeography, tectonic, rock assemblage, the Doushantuo formation thickness, moraine-breccia thickness as predictor variables, use of rank correlation coefficient method; analysis of the prognostic factors, determine the deposit location prediction factors key variable interval. Through the characteristic analysis of prognosis factors analysis, we identify 34 forecasting area of class A based on the MRAS software. |
