摘　　要：综合地质、地球化学等资料进行多元信息成矿预测是目前深部固体矿产主要工作方法。广东仁化县书楼丘铀矿床位于诸广南铀矿田北部,是诸广南铀矿田重要的组成之一。本次为了拓宽书楼丘矿床深部找矿思路,探讨其找矿潜力,在前人研究和勘探基础上,总结了矿床综合信息找矿模型,以三维定量预测研究理论基础,根据矿床成矿条件和找矿标志特征,提取地质、化探、钻探资料的成矿有利信息,并利用COCAD软件构建了地形-地表、岩体、构造、矿体等地质模型,对信息进行综合成矿有利分析,运用信息量法进行研究区深部矿产资源预测,共圈定了3片靶区。Multi-information mineralization prediction based on geological,geochemical and others data is the main working method for deep solid minerals.In order to broaden the prospecting ideas in the depth of Shulouqiu deposit and discusses its prospecting potential,on the basis of previous research and exploration,the comprehensive information prospecting model for ore deposits is summarized.This work builds on the theory of 3D quantitative prediction,metallogenic conditions and characteristics of prospecting marks,to extract favorable information of mineralization from geological,geochemical and drilling data.Using the GOCAD software,geological models are constructed,which characterize the surface-topography,rock mass,structure,and orebody,respectively.The favorable information of mineralization is analyzed,mineral resources at depth are predicted using the information value method,and three target areas are delineated in the study area.
