【摘要】 本文利用我国西北部喀什—乌鲁木齐、乌鲁木齐—高台的瑞利波相速度和喀什—高台的瑞利波群速度进行反演,得到了三个剖面的地壳结构的层状模型。结果表明:三个剖面的频散曲线和地壳结构彼此不同,说明我国西北部地壳结构的横向变化显著。更多还原

【Abstract】 The lamellar models of the crust structure of three profiles are achieved in this paper by means of the reverse of the velocities of Rayleigh wave swarms from Kashi to Gaotai and the phase velocities of Rayleigh wave from Kashi to Urumuqi and from Urumuqi to Gaotai. The results show that the frequency curves of scatterness for the three profiles and the crust structure are different each other, which means there is a very obvious transverse variation of the crust structure in Northwestern China.更多还原
