将对盆地-山脉地壳进行多分量地震反射、大地电磁、构造和岩石学研究,以研究地壳流体问题,包括莫霍岩浆、隆起核杂岩下的地壳流入、底板、地壳中剥离带、各向异性和下地壳性质。红宝石山岩心复合体的结构崩塌,产生了大于10公里的暴露水平差异,为研究这些问题提供了一个特别好的环境。纵波和横波与地壳深部电导率的结合为约束盆山地壳的各种可能性提供了很好的机会,特别是因为地震和MT结果在解释导电带方面是相互补充的。数据采集涉及约1550个地震通道,旨在优化s波数据以获得最大分辨率,地震和大地电磁法解释中的分辨率问题是得出结论的主要考虑因素。地球物理解释得到的模型将与岩石学和构造相结合。
英文摘要
Multicomponent seismic reflection, magnetotelluric, structural, and petrological studies of Basin-and-Range crust will be performed to study problems of fluids in the crust including magma at the Moho, crustal inflow beneath uplifted core complexes, underplating, mid-crustal detachment zones, anisotropy, and nature of lower crust. Structural plunge of the Ruby Mountains core complex, producing greater than 10 km difference in level of exposure, offers a particularly good setting to study these problems. The combination of S-waves as well as P-waves together with conductivity in the deep crust provides a good opportunity to constrain various possibilities suggested for Basin-and-Range crust, especially because seismic and MT results complement each other in explaining conductive zones. Data acquisition involving about 1550 seismic channels is designed to optimize S-wave data for maximum resolution, and the question of resolution in seismic and MT interpretation is a major consideration in developing conclusions. Models obtained from geophysical interpretation will be integrated with petrology and structure.
