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.
