初论秦岭造山带超大型金属矿集区研究与勘查技术

SUPER LARGE DEPOSITS-CONCENTRATED AREA IN QINLING OROGENIC BELT AND THE EXPLORATION TECHNIQUES

层控矿床理论运用及岩相古地理研究、综合方法普查与系统评价、普查与科研并举是发现厂坝—李家沟超大型铅锌矿床、李坝及金龙山超大型金矿集区、八卦庙超大型金矿床的主要勘查方法技术。认为秦岭造山带中大型—超大型矿（ 床） 集区的主要勘查标志有：三级热水沉积成矿盆地是聚矿的构造空间；同生断裂是成盆－ 成矿的主控因素。热水沉积岩相发育齐全及分异良好是热水层流体系形成；不同成分、性状的热水混合体系中，多组分、多因素及多过程耦合是热水成矿作用的地球化学动力学特征。提出超大型金属矿床的勘查方向及建议。

The Changba Pb-Zn deposit, Liba gold deposit, Jinlongshan gold deposit and Baguamiao gold deposit are recently discovered in Qinling orogenic belt. The third-rank subbasin with extensively hydrothermal deposition is the main ore-hosting space.. The contemporaneous faults are the main controls on basins and ore deposits. On the basis of the foregoing discussion, the metallogenesis and metallogenic geochemical dynamics are studied. The prospecting orientation and suggestions are put forward. The non-conventional exploration methods should be initiated.
