秦岭造山带是我国重要的有色金属和贵金属成矿带,对其研究表明,多数金属矿床具有成矿物质多源、成矿时代多期、矿床成因复杂等共性特征,但是这些矿床一般受早期初始富集成矿和晚期造山改造就位的二元因素控制,矿床的富集空间主要为断裂构造、褶皱虚脱部位和印支-燕山期侵入体内外接触带.在总结秦岭造山带金属矿床成矿规律的基础上,我们提出秦岭造山带金属矿床的"二元控矿"作用,旨在总结关键控矿因素,指导区域找矿勘查.

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 ore-genesis. 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 ore-controlling 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.
