摘要:

选取豫西南杜关—云阳钼多金属成矿带为研究区,利用多学科资料,使用非线性方法提取了多元、多维、多尺度、多类型找矿信息。在应用层次分析法集成多元信息的基础上,进一步用“Kriging+Natural Breaks”和C-A分形法分别圈定了找矿靶区。结果表明,两者所圈定的找矿靶区基本一致,但后者在局部地段能够更细致地刻画靶区的细节,将找矿靶区进一步划分为Ⅰ、Ⅱ、Ⅲ级。其中Ⅰ、Ⅱ级预测区内包含有已知矿床,Ⅲ级预测区具有较好的找矿潜力。该成果为本地区的下一步找矿工作提供了依据。

Abstract:

Taking DuguanYunyang district as a case study area, according to the multidisciplinary data, using nonlinear mathematical method, the geological prospecting information of multivariate, multi-scale, multi-dimension  and multi-type is extracted. AHP method is selected to integrate prospecting information. On this basis, using two different combinatorial methods of “Kriging+Natural Breaks” and C-A fractal method, molybdenum polymetallic mineralization favorable targets are calculated and delineated. The results show that the main targets of the study area delineated by these two methods are same, but C-A fractal method can identify local mineralization favorable targets and can more deeply divide the targets. Combined with degree of regional exploration and mineral geological data, the targets delineated by C-A fractal method are further divided into three grades, ie, grade Ⅰ, Ⅱ and Ⅲ. The result shows that most known deposits are located in gradeⅠ,Ⅱ further prospecting areas,and Ⅲ area is a favorable prospecting area. Furthermore, the result offers a basis for further exploration.

Key words: C-A fractal method, analytic hierarchy process, molybdenum polymetallic ore, southwest Henan Province, metallogenetic prediction
