在模拟地壳的温度和压力条件下，测定了华北地台太行－五台和阴山地块的主要变质岩群和侵入岩共５４个岩石样品的纵波速度（ｖｐ）．各类岩石的ｖｐ在约４～１０ｋｍ深度内上升很快，在１０～２５ｋｍ内继续增大，但是幅度变小，在该深度范围内达到了ｖｐ最大值；在３０～３５ｋｍ之后到５０ｋｍ深度内的ｖｐ都趋于恒定．综合对比地壳的波速结构和岩石的波速特征表明，在太行－五台地块，五台群、滹沱群和古老花岗岩岩类构成上地壳，阜平群和恒山群构成中地壳，集宁群代表了下地壳的岩石组成；在阴山地块，马家店群、二道凹群、色尔腾山群和古老侵入岩类是中地壳和上地壳的组成部分，乌拉山群岩石则是下地壳的代表
Under simulated conditions of temperature and pressure of the crust, the longitudinal wave velocity (vp) of 54 rock samples from the main metamorphic rocks and intrusive rocks of the Taihang-Wutai and Yinshan blocks in North China is measured. The vp of all kinds of rocks rose rapidly in the depth of 4 ~ 10km and continued to increase in 10 ~ 25km, but the amplitude became smaller, reaching the maximum of vp in this depth range. Within 30 ~ 35km to the depth of 50km The vp tends to be constant. The comprehensive comparison of the crustal wave velocity structure and the rock velocity shows that the upper crust is formed in the Taihang-Wutai block, the Wutai Group, the Hutuo Group and the ancient granite, and the Fuping Group and Hengshan Group constitute the middle crust. Lower crust; rocks in Yinshan, Majiadian, Erdaowan, Sertengshan and ancient intrusions are part of the middle crust and the upper crust, while the Wulashan fossils are lower crust representative
