摘　　要：覆盖区矿产预测和地质找矿是一项具有探索性的研究课题,需要解决覆盖区各种致矿信息存在的"弱缓"、"叠加复合"、"缺失和不完整"等缺陷,从而有效地获得指示覆盖层之下矿化体的致矿信息.识别优势矿种和矿化类型、建立区域成矿-找矿模型,采用多重分形预测理论和方法,都将有利于强化和提取现有资料和数据中的致矿信息.提出了一个初步的覆盖区综合地质找矿流程框架,并结合实际研究工作认识,以内蒙古锡林郭勒西北部为例,介绍了采用这种覆盖区综合地质找矿流程进行草原覆盖区综合地质找矿的做法及其初步结果.Geological prospection in covered areas is an important issue,which is confronted with a series of problems to be worked out,such as overcoming ore-generated messages faults ranging from weak to sluggish,overlapping,absent to uncompleted faults and to gain effectively the ore-generated information associated with ore bodies in the covered areas.Identifying the main ore elements and type of mineralization,establishing a regional model of ore genesis-prospection and using the method of nonlinear integrated prediction should be better to strengthen and extract mineralized information from the existing geological data.A primary framework of a new approach on integrated geological prospection in covered areas is presented in this paper.With a case study of Northwestern Xilinguole of Inner Mongolia,it shows the approach and result in detail of its application to grassland-covered area for integrated geological prospection.
