将有限差分层析反演方法用于大别造山带人工地震测深剖面上部地壳初至波的走时层析成像，得到这一剖面上部地壳横向不均匀结构图像表明，在南大别地区的超高压变质带发现榴辉岩相岩石，其下方3km深度以内的基底仍具有大陆地壳构造中正常的结晶基底速度（6．00km／s左右）；北大别地区在整个上地壳保持正常的速度，而在超高压带下方3km深度以下为6．20—630km／s的相对高速异常区，这一现象可能与超高压变质岩的含量增大有关．同时还表明，南大别和北大别之间至少在上地壳已有明显差异，它们之间的水吼一五河断裂可能是大别造山带内部的主要构造分界线．
The finite difference tomography inversion method is applied to the traveltime tomography of the first crust of the upper crust in the artificial seismic sounding profile of the Dabie orogenic belt. The lateral crustal structural image of the upper crust in this section shows that in the Dabie area, Metamorphic belt found eclogite facies, the base within 3 km below the depth of the continental crust still has the normal crystalline basement velocity (6.00km / s or so); the North Dabie area throughout the upper crust to maintain normal speed, while in the The relatively high-velocity anomalous zone below 6. 3 km below the UHP zone is 6.20-630 km / s, which may be related to the increase of the content of UHP metamorphic rocks. At the same time, it also shows that there is at least obvious difference between South Dabie and North Dabie in the upper crust. The water rift-Wuhe fault between them may be the main tectonic dividing line within the Dabie orogen.
