【摘要】 利用天然地震和工程爆破在莫霍界面上的反射波和首波测定地壳厚度的方法，求出临汾地区的地壳平均厚度为３８ｋｍ，侯马、介休地区３７ｋｍ，吕梁山区４４ｋｍ，太行山区４３．５ｋｍ。指出沿临汾盆地汾河河谷有深大断裂存在，地壳深部莫霍间断面为─上隆的条状地带与地面的ＮＮＥ向断陷盆地相对应。更多还原

【Abstract】 Using the met hod of the crustal thickness explored by the reflection wave and the hed wave of natural earthquake and engineering explosion on the Moho discontinuity,the paper derived that the average crustal thickness in Linfen region is 38 km,Houma and Jiexiu 37km, Luliang mountainous region 44 km,Taihang mountainous region 43.5km.Suggested that there is a deep fracture along the valley of Fen river in Linfen basin, the Moho discontinuity is a uplift banded zone corresponding the NNE rift basin.更多还原
