豫西南杜关-云阳钼多金属成矿预测研究
Research on Molybdenum Polymetallic Metallogenic Prognosis in Duguan-Yunyang District,Southwest Henan Province
摘要
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, multidimension 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 grade Ⅰ, Ⅱ further prospecting areas, and Ⅲ area is a favorable prospecting area. Furthermore, the result offers a basis for further exploration.关键词
