Abstract: Recent years,with prospecting for Cu deposit has got great success in the area adjacent of Inner Mongolia,as well as a series of important new evolvers in Cu ore prospects have got in Inner Mongolia,to prospect Cu deposit in Inner Mongolia has bringed the attentions of the geologists at home and abroad.The geological structure and Cu deposit explored and new information of geochemistry related to Cu deposit show that there are huge potentials for prospecting Cu deposit in this region.Analyzing and summ arizing the cha racteristics of distribution of Cu deposit and Cu abnorml,the authors make off three Cu ore-forming zones,circled Cu deposit or abnorml forestation furthe,and put forward the direction for prospecting large and ultralarge-scale Cudeposit.
