甘肃中南部与埃达克质岩有关的斑岩型Cu、Au矿成矿规律与找矿方向

The Metallogenetic Regularity and Prospecting Guide of Porphyry-type Cu and Au Deposits Related to Adakitic Rocks in the Central and Southern Gansu

通过对甘肃中南部祁连造山带中、东段和西秦岭西段部分地区埃达克质岩体分布特征和成岩成矿的构造背景及其演化过程的研究,分析了与其相关的斑岩型Cu、Au矿床的成矿规律、成矿地质条件和埃达克岩型Cu、Au矿成矿模式,为该地区确定更有效的找矿勘探方向及勘探部署提供指导和理论依据。

The paper has researched the geological features,temporal-spatial distribution and tectonic evolution of mineralization of the Adakitic rocks in the central and eastern sections of Gansu Province,and in the western part of West Qinling.It analyses the porphyry-type Cu and Au deposits related to adakitic rocks,especially about the metallogenetic regulations and geological contraints,and metallogenetic model of adakite-type Cu and Au deposits, and provides a guidance and theory for Cu-Au-prospecting exploration in this area.
