摘要
甘肃北山地区是一重要的金矿化集中区,具较大的金资源潜力。由于勘查和研究程度低,尚未取得找矿突破。本文从金矿的空间分布、金矿床的地质特征、花岗岩的时空分布、金矿与花岗岩的时空关系和矿床的稳定同位素特征等的研究,探讨了本区金矿成矿作用与花岗岩类侵入活动的关系。研究该区花岗岩类的时空演化及其与金成矿作用的关系的研究,对于寻找和勘查金矿,以实现该区找金的突破具有重要的实际意义。
The Beishan region in the western Gansu Province is an important gold mineralization concentrical area with the great gold potential,but no breakthrough have been got due to the low level of exploration and research.The paper analyzed the relation between gold metallogenesis and the activities of granite intrusion from such aspects as spatial distribution and geological features of gold deposits,distribution of granitoid,and the spatial and time relation between gold deposits and granitoid,as well as the stable isotope.
