闽北地区 头—下柳源一带伟晶岩型铌钽矿产远景预测

Long-range Perspective of Pegmatite-Type Columbotantalite in FuTou-Xialiuyuan Area of Northern Fujian

通过特征分析模型分析和变量选取及关联度分级,对闽北地区头—下柳源一带伟晶岩型铌钽矿产进行远景预测研究。运用特征分析模型(Ⅰ-Ⅳ)计算统计矿床的关联度,对已知矿床模型单元进行检验及对未知统计矿床进行预测,并进行远景预测分级。

In the paper the long-range prediction of the pegmatite-type columbotantalite in FuTou-Xialiuyuan area of Northern Fujian is under discussion according to the characteristic analysis, model analysis, variant selection and the classification of association degree. It evaluates and reckons among the degree of deposit association by using patterns （Ⅰ-Ⅳ） of characteristic analysis, checks up the known mineral deposit modeling and forecasts the unknown deposits from the statistic results. Finally, it makes a classification of the longrange perspective of pegmatite-type columbotantalite.
