摘要
The metallogenic conditions of marine volcanic type lead-zinc resources in the metallogenic belt of northern Qilian Mountains was analyzed by means of GIS. A prognostic model for lead-zinc ore deposits was established and the factors for mineral prediction were extracted and assigned values by graded-WOE. The favorable prospecting areas were delineated. The weighing of prediction of marine volcanic type lead-zinc resources includes strata, magmatite, structure, and other related quantitative factors were determinated. Finally, the study areas were delineated into mineralization prospective zone Ⅰ and Ⅱ by posterior probability values.
