Abstract:
The Qinling orogenic belt is one of important nonferrous and rare metal metallogenic belts. Study shows that most deposits in the Qingling orogenic belt are characterized by multiple material sources, multiple mineralization stages and complicated oregenesis. But these deposits are generally controlled by two factors, i.e. early initial enrichment mineralization and late orogenic reformation emplacement. The space for mineralization enrichment consists mainly of fault structures, fold collapse parts, and the contact zones between the Indosinian and Yanshanian plutons. In combination with the analysis of the metallogenic regularity of the Qinling orogenic belt, we firstly proposed the “Dual orecontrolling factors” concept for metallic deposits formed within the Qinling orogenic belt for the purpose of summarizing the key metallogenic controlling factors and further direct to regional prospecting.
