9418251 Knapp This award supports US collaboration with European and Russian colleagues in the acquisition and analysis of a 500km seismic reflection profile across the Uralian orogen in central Russia. The proposed transect through the southern Urals extends from the East European platform in the Uralian foreland to the West Siberian basin, crossing the Bashkirian foreland fold and thrust belt, the Kraka ophiolite, the Main Uralian fault (suture zone), a collage of oceanic and microcontinental terranes in the hinterland, and the main axis of orogenic magmatism. The data to be acquired will provide the first complete seismic image of the crustal and upper mantle architecture of an intact Paleozoic orogen, and contribute potentially fundamental new insight into the processes of continental collision and subsequent orogenic evolution. Project URSEIS (Urals Reflection Seismic Experiment and Integrated Studies) represents an international collaboration of unprecedentd scale in deep seismic profiling. The US contribution leverages a larger EUROPROBE outlay, principally from DEKORP (Germany) and ROSCOMNEDRA (Russian Committee for Geophysics and Deep Drilling). The program derives from two years of planning, including evaluation of existing Russian geophysical and geological data for the Urals, and follows a successful multi-national pilot survey in 1993. ***

9418251 Knapp 该奖项支持美国与欧洲和俄罗斯同事合作采集和分析俄罗斯中部乌拉尔造山带的 500 公里地震反射剖面。 拟议穿过乌拉尔南部的横断面从乌拉尔前陆的东欧地台延伸至西西伯利亚盆地，穿越巴什基尔前陆褶皱和冲断带、克拉卡蛇绿岩、乌拉尔主断层（缝合带）、腹地的海洋和微大陆地体拼贴以及造山岩浆作用主轴。 即将获取的数据将提供完整的古生代造山带的地壳和上地幔结构的第一张完整地震图像，并为大陆碰撞和随后的造山演化过程提供潜在的基本新见解。 URSEIS 项目（乌拉尔反射地震实验和综合研究）代表了深层地震剖面方面前所未有的规模的国际合作。 美国的贡献利用了更大的 EUROPROBE 支出，主要来自 DEKORP（德国）和 ROSCOMNEDRA（俄罗斯地球物理和深钻委员会）。 该计划源自两年的规划，包括对俄罗斯乌拉尔地区现有地球物理和地质数据的评估，并遵循 1993 年成功的多国试点调查。***
