| 中文摘要: |
| 文章对滇东地区在分析、建立致矿地质异常概念模型的基础上,以东川-曲靖图幅为例,探讨了采用铂钯地球化学异常与各种成矿有利地质标志相结合计算成矿有利信息量和单元总信息量,进行无模型指导下的定量成矿预测和评价的方法,圈定、评价了铂钯找矿可行地段5处,找矿有利地段3处,认为有一定的找矿潜力,可供找矿解剖验证.同时指出了该方法普遍适用于其它矿种的预测、评价及其诸多优点. |
| 英文摘要: |
| Base on analyzing and setting up the ideal model of ore-forming geo-anomaly in the eastern Yunnan province, this paper firstly discussed how to calculate ore-forming advantage information and total information using combination of Pt and Pd geochemical anomaly with various ore-forming advantaged geological indications, and then investigated quantitative ore-forming prediction and assessment methods of no model in the Dongchuan-Qujing area for an example. Five permissible ore-finding areas and three preferable ore-finding regions with positive potential to find ores have been delineated and evaluated for further dissection and testifying. This advantage method can be used in ore-forming prediction and assessment for other mineral kinds. |
