| 摘 要： | 沿着亚东－格尔木地学断面，由地质，地球物理和地球化学综合数据，给出岩石圈演经的一般图像，青藏高原系由６个地体组成的；高原在垂向与横向是不均匀的，各地体间的组构是不同的；高原地壳的缩短与隆升是因素的，包括其中向北运动的印度板块的挤压作用及柴达木盆地阻力，地幔热活动比预期要差；喜马拉雅山带不同于安第斯山和阿尔卑斯山，有其自己的特征。

| Abstract: | Geological,geophysical and geochemical data have been combined to give a general picture of the evolution of the lithosphere along the Yadong-Golmud geoscience transect.The Qinghai-Tibet Plateau,composed of six distinct terranes,is heterogeneous both laterally and vertically and its tectonic fabrics vary between the terranes.The shortening,thickening and uplift of the crust have been caused by a variety of factors,including compression due to northward movement of the Indian plate,resistance to such movement by the material in the Qaidam Basin region,and isostatic effects on both the crust and mantle.Thermal activity in the mantle is less important than that in the crust.The Himalayan orogenic belt has some important features that distinguish it from the Andean and Alpine orogenic belts. |
