Abstract

Deep velocity models of the lithosphere of the Khoper Block and Losevskaya Suture Zone of the Voronezh crystalline massif of the Sarmatia Protocraton are obtained for the first time by the receiver function technique. The crust is determined by a four-layered structure with a waveguide in the lower part of the section. The presence of a zone of lower velocities in the upper mantle at depths of 110–150 km, which mark the mid-lithospheric discontinuity (MLD), as well as their characteristics, is identified for the first time for the Khoper Block. A complex, probably, gradient structure of the crustal–mantle transition is determined.

新的地震数据显示的萨尔马特原核东北部岩石圈

摘要通过接收函数技术，首次获得了萨尔马特原核沃罗涅日结晶地块霍珀区块和洛舍夫斯卡娅缝合带岩石圈的深速度模型。地壳由四层结构组成，断面下部有波导。在 Khoper 区块，首次确定了上地幔 110-150 千米深处存在一个速度较低的区域，标志着岩石圈中部的不连续性及其特征。确定了地壳-地幔过渡的复杂梯度结构。
