层次分析法在冀北地区多金属矿找矿预测中的应用
Application of analytic hierarchy process method to ore-prospecting prognosis in northern Hebei
摘要
Abstract
North Hebei geotectonic unit includes North China craton, Tianshan-Xingmeng orogenic system and China's eastern orogenic mountains-rift system.Archean metamorphic rocks are widely distributed, the magmatic intrusion-eruption activities of Hercynian and Yanshanian period are frequent and, what is more, wallrock alterations are widely spread in this area;therefore, polymetallic deposits are likely to be found in this area.According to the relationship between the remote sensing geological interpretation factors, alteration remote sensing anomalies and the mineralization, the author selected the linear and ringed structures in medium space resolution remote sensing images and alteration remote sensing anomalies, intrusive rocks, ore formation and mineral distribution information as judgment factors, and established the prospecting prognositic models by AHP (Analysis Hierarchical Process).As a result, 29 prospecting target areas were delineated, 5 superlarge ore deposits were found in 3 prospecting target areas, and 12 medium-sized ore deposits were found in 6 prospecting target areas.The results indicate that polymetallic ore prospecting prediction and delineation of prospecting targets can achieve good effect by AHP in northern Hebei area.关键词
