青海省北半部主要指纬度36°以北的广大地区,包括柴达木盆地北缘(海西)、祁连山系(海北)、和东部农业区(东部)。在这个范围内陆相侏罗系地层广泛出露,并有丰富的煤炭资源,故解放以后党和政府对这一带的地质情况十分关心,陆续地进行了普查与勘探,累积了大量资料。今为适应煤田予测和发展国民经济的需要,特将地层工作方面的情况作一概略的总结和讨论,不妥之处请指正。
The northern half of Qinghai Province mainly refers to the vast area north of latitude 36 °, including the northern margin of the Qaidam Basin (Hercynian), the Qilian Mountains (Haibei), and the eastern agricultural zone (east). In this area, the continental Jurassic formations are widely exposed and rich in coal resources. Therefore, the party and government after the liberation are very concerned about the geological conditions in this zone. Census and exploration have been carried out one after another, accumulating a large amount of data. In order to meet the needs of the coalfields for the purpose of forecasting and developing the national economy, we should give a general summary and discussion of the stratigraphic work situation. Please correct any irregularities.
