| 摘 要： | 本文应用地质力学的理论和方法,划分了青海都兰地区构造体系,讨论了其成生发展和演化历史。指出区域东西向构造、南北向构造和西域系是成矿前构造体系。本区主要的控矿构造体系是青藏歹字型(头部外围褶带)和河西系,并确定了主要控矿构造型式。文中还讨论了构造体系对区内沉积建造、岩浆建造,矿产分布规律的多级控制作用和构造体系复合的控矿作用。

| Abstract: | A study of the formation and evolution of the tectonic systems present in the area and their relation to mineralization shows that the E-W- and N-S-trending structures and the West China system are pre-mineralization tectonic systems, and that anterior peripheral fold-belt of the Qinghai-Tibetan eta-type structure and the Hexi system are the main ore-control-ling tectonic systems.In addition, a discussion is also made on the tectonic system control of sedimentary formation and magmatism, and on the control of ore by different orders of struc-tures of a tectonic system as well as by their compounding. |

| Keywords: | structural control of ore ore-controlling tectonic systems |
