矿床成矿系列综合预测模型

On integrated prognosis model for metallogenic series

以香格里拉地区与印支期中酸性斑(玢)岩有关的有色金属成矿系列为例,探讨了矿床成矿系列综合预测模型的建立方法及过程。认为成矿系列的不同序次均应有与之相对应的预测模型,只有将不同级次的预测模型结合起来,相互补充,才能更好地完成从面上评价到点上突破的找矿预测过程。综合预测模型建立的好坏,直接影响基于成矿系列的全位预测和缺位预测。

Nonferrous metal metallogenic series related with intermediate-acid porphyry of Indosinian period in Shangri-La were chosen as a case study in the text, the authors discussed the way of building a metallogenetic series integrated prediction model. The authors indicated that different prognosis models should be built corresponding to different grades of metallogenie series, which not only could be used in regional survey but also in occurrences and spots prediction.
