The SW-NE directed wide-angle reflection-refraction (WARR) SHIELD’21 profile crosses entire width of Ukraine. It targeted the structure of the crust and uppermost mantle in the southwestern part of the East European Craton (EEC), between Carpathians and Voronezh Massif, across Ukrainian Shield and Dnieper-Donets Basin. The ∼660 km-long profile is an extension of the RomUkrSeis profile in Romania and Ukraine. SHIELD’21 experiment, using TEXAN and DATA-CUBE short-period seismic stations, provided high-quality seismic sections from 10 shot points. This allowed construction of a ray-tracing P-wave velocity model, supplemented by Vp/Vs ratio, for the upper part of the lithosphere in the Sarmatia segment of the EEC and constraining geodynamic processes that led to the formation of the Ukrainian Shield and its margins since Archean times.

从喀尔巴阡山脉到第聂伯河-顿涅茨盆地的乌克兰地盾地震岩石圈模型及其构造解释


SW-NE 定向广角反射-折射 （WARR） SHIELD'21 剖面横跨乌克兰的整个宽度。它的目标是东欧克拉通 （EEC） 西南部的地壳和最上部地幔的结构，位于喀尔巴阡山脉和沃罗涅日地块之间，横跨乌克兰地盾和第聂伯河-顿涅茨盆地。∼660 公里长的剖面是罗马尼亚和乌克兰 RomUkrSeis 剖面的延伸。SHIELD'21 实验使用 TEXAN 和 DATA-CUBE 短周期地震站，从 10 个射击点提供了高质量的地震切片。这允许为 EEC 的 Sarmatia 段岩石圈的上部构建射线追踪 P 波速度模型，并辅以 Vp/Vs 比率，并限制了导致乌克兰地盾及其边缘形成的地球动力学过程自太古宙时代以来。
