甘肃龙首山多金属成矿带地质构造特征研究

Study on Geological Structural Characteristics of Longshou Mountain Polymetallic Metallogenic Belt in Gansu Province

本文通过对甘肃某多金属成矿地带矿床的深入研究,通过古元古代陆块形成和碰撞阶段、中元古代龙首山边缘沉降带形成以及震旦纪边缘沉降带沉降阶段分析了多金属成矿带的成矿地质条件和成矿机制,建立成矿模式。

Based on the in-depth study of the deposits in a polymetallic metallogenic belt in Gansu Province,this paper analyses the metallogenic address conditions and metallogenic mechanism of the polymetallic metallogenic belt through the formation and collision stages of Paleoproterozoic landmass,the formation of the marginal subsidence zone of Longshou Mountain in the Mesoproterozoic and the subsidence stage of the Sinian marginal subsidence zone,and.
