荷泽—长治剖面是国家地震局物探大队于1981年完成的地震测深剖面。其结果进行计算处理后发现,在以汤阴地堑为中心,深约20公里处存在一个东西延伸约100公里、厚约4公里、速度值6.6~6.8公里/秒的高速异常体.从它与周围介质的速度差(约0.5公里/秒)以及形态分布特征看,高速异常体的物质很可能来自上地幔,它借助于上拱的莫霍面上升至中地壳,甚至可能顺着地堑的张裂隙升迁到地表.我们认为:
Heze - Changzhi section of the National Seismological Bureau of Geophysical Brigade completed in 1981, the seismic sounding profile. The result of calculation shows that there is a high-speed anomalous body extending about 100 km deep, with a depth of about 4 km and a speed of 6.6-6.8 km / s, about 20 km deep with the Tangyin grab. Depending on the velocity difference (about 0.5 km / s) and the morphological distribution of the surrounding medium, it is likely that the high-velocity anomalous material is likely to originate from the upper mantle, rising to the mid-crust with the help of the arched Moho, possibly even along the graben Zhang crack up to the surface. We think:
