| 摘 要： | 基于成矿系列理论和GIS为平台的综合信息找矿预测理论方法，梳理分水岭北地区地质背景，分析成矿地质条件，总结铜金成矿规律和成矿模型，建立找矿模式，析出研究区金铜矿产可能的5个成矿系列，并以综合信息法、逻辑信息量法、找矿信息量法做成矿预测，圈划找矿靶区8处，优选出3个A类找矿靶区。对比分析5种找矿靶区的圈划方法后认为，定量以定性为基础，是定性过程和结果的定量表达，并能规范化、精细化、客观化定性的过程和结果，防范定性过程和结果的主观错漏。

| Abstract: | The northern watershed area lies in the western end of East-kunlun and Animaqing metallogenic belts. On the basis of the theory of metallogenic series and comprehensive information prospecting prediction, the authors analyzed the geological background and the metallogenic geological conditions of the study area, summarized the metallogenic regularity, the regional prospecting model and five possible metallogenic series of gold and copper deposits. Comprehensive information method, logical information method, and ore prospecting information method were used to make the metallogenic prediction. 8 copper and gold prospecting targets were delimited, among which 3 were A-type. By comparing the five ways of delimiting the ore-prospecting target area, it is held that quantitative method, which is based on the qualitative method and is the quantitative expression of the qualitative process and result, can prevent the subjective errors in the qualitative process and result. |
