| Abstract: |
| The present paper deals, in detail, with western China the major aspects of the geology, tectonics and mineral resources in the Qiangtang-Hol Xil region, western China, including the presence or absence of the basement in the Qiangtang Basin, the discovery of schist and pyrolite in eastern Margog Caka, the Lungmuco-Shuanghu suture zone, NS-trending structures, ages of the Cenozoic volcanic rocks, the absence of the Early Cretaceous deposits in most parts of the basin and significant contact relations. Particular attention should be paid to the oil-gas and fresh-water resources in the basin and the collection of meteorological information in the future regional geological investigation. |
