摘要:
提要:本文基于矿床地质特征研究的基础上,采用“MORPAS”软件平台,对矿区地质、化探、遥感等地学多元信息进行综合分析,厘定了找矿模型,开展了研究区的综合信息成矿预测,圈定了4个找矿靶区,并根据矿床值随各控矿因素及其组合的变化规律,选取一定的模型单元,建立控矿因素及找矿标志的综合值——信息量与资源量之间的函数关系,并对圈定的4个靶区的资源量进行定量估算,对研究区进行资源潜力评价,对该区下一步的找矿工作具有重要的指导意义。

Abstract:
Abstract:Based on researches on geological features of the ore deposit, the authors carried out a systematic study of the Balao ore district to obtain useful metallogenic information. The software platform “MORPAS” was used to analyze comprehensively large amounts of geosciences multi-information in the aspects of geology, geochemistry and remote sensing. A prospecting model was set up to perform the metallogenic prediction on comprehensive information of the study area and, as a result, four prospecting targets were delineated. Certain model units were selected according to the variation regularity of the deposit value with the ore-controlling factors and their combinations so as to establish the comprehensive value of ore-controlling factors and prospecting criteria, i.e., the functional relationship between the information and the resources, and the resources of four prospecting target areas were estimated quantitatively. The evaluation of the resource potential is of important guiding significance for the next step prospecting work in the study area.
