Abstract: Affected by thrust nappe and strike-slip movement in the integrated exploration area of manganese deposit in Chengkou County,a large number of faults and folds has been formed,all of them belong to the ore-breaking structures after metallogenic period.According to the structural forms of faults and folds in the study area,it can be divided into three zones of structural forms,which include the zone of right strike-slip faults and thrust faults,the zone of left strike-slip faults,right strike-slip faults and thrust faults and the zone of folds and faults.Based on the characteristics of tectonic evolution in the study area,the evolution of the orebodies experienced four stages,which include the sedimentary stage,the fold bending stage,the fault failure stage and the uplift transformation stage.By the analysis of the structural combination characteristics of the study area,the structural ore-controlling regularities of the study area is summarized,which is of great significance to guide the drilling location in manganese exploration work,improve the percentage of ore-occurrence and realize the breakthrough of prospecting in the study area.

Key words: Manganese deposit, Structural combination, Ore-controlling model, Structural evolution, Ore-controlling regularity
