| 摘 要： | 提出了西藏羌塘地区的六个地质构造问题。包括冈瓦纳与欧亚大陆古特提斯界线；羌塘地区是否存在加里东期或更古老基底；羌塘地区的地层系统及其对比；狮头山、黑熊山一带蓝片岩的地球动力学意义；龙木错─双湖蛇绿岩的性质、成因及年代；羌塘盆地中三叠世以前是一个统一的盆地还是分属两大陆的边缘海盆等。这些问题的解决将有助于更加清楚、完整地认识青藏高原的地质历史过程。 |

| Abstract: | Six issues were put foward, following as, the boundary of the PaleoTethys between the Gondwana and Eurasia continents, the basement character andtexture, the stratigraphic system and correlation,the significance of the blue schists in theLion Mountain,Black Bear Mountain and Yingchunkou areas, the age and mechanism ofLongmucuo -Shuanghu ophiolite, the characteristics of the Qiangtang basin (it was thesame basin or belonged to different marginal sea basins of two continents before Mid Triassic).Many crucial tectonic problems of above will help us in revealing the Qinghai-Tibetplateau more clearly and completely. |
