| 中文摘要: |
| 马场台金矿区位于青海省湟源县境内,属于秦祁昆地层区,该区为前寒武系隆起,主要出露元古宙变质岩系。地层走向多呈北西—南东向,与区域构造方向基本一致。区内大地构造位置位于祁连造山带东段,古特提斯构造域北侧,位于中祁连铜、铁、非金属成矿带。该区地质构造复杂,岩浆活动强烈,成矿事实较多。本文对青海省马场台金矿地球物理化学地质特征及找矿前景进行了分析探讨,以供参考。 |
| 英文摘要: |
| The Machangtai gold mining area is located in Huangyuan County,Qinghai Province,which belongs to Qin Qikun stratigraphic area. The area is a pre-Cambrian uplift,mainly showing Proterozoic metamorphic rocks. The strata tend to be NW-SE,which is basically consistent with the regional tectonic direction. The geotectonic position in the area is located in the eastern section of Qilian orogenic belt,to the north of the Paleotethys tectonic domain,and in the copper,iron and nonmetallic metallogenic belt of the central Qilian. The geological structure in this area is complex,magmatism is intense,and there are many ore-forming facts. In this paper,the geophysical,chemical and geological characteristics and prospecting prospects of Machangtai gold deposit in Qinghai province are analyzed and discussed for reference. |
