CALCRUST: A Regional Study of Crustal Structure and Evolution

该提案要求为下一年继续开展加州地壳研究联合会(CALCRUST)活动提供资金。CALCRUST是一个由来自加州机构的地球科学家组成的联盟，他们对地壳结构和演化有着共同的兴趣。CALCRUST科学团队包括具有从区域地质学到反射地震学和地震数据处理的专业知识的个人。CALCRUST计划继续解决美国西南部的重要科学问题，包括大陆增生构造、地壳伸展和挤压的力学、美国西南部地震孕育区的变形模式、岩浆岩的结构以及加州沿海含油气盆地的基底构造。CALCRUST寻求在地震剖面中携带从露头到深度的构造关系，并希望研究地下反射数据可以与地下流变学和岩石化学直接相关的技术，例如通过使用横波和地震速度分析。CALCRUST在授标期间的活动将包括对现有数据集的数据处理和随后的分析，以及(与美国地质勘探局和斯坦福大学一起)参与一项试验性研究，以成像旧金山湾区的地壳结构和活动断层。

This proposal requests funds to continue CALCRUST (California Consortium for Crustal Studies) activities for the next year. CALCRUST is a consortium composed of earth scientists from California institutions with a common interest in crustal structure and evolution. CALCRUST scientific teams include individuals with expertise ranging from regional geology to reflection seismology and seismic data processing. The CALCRUST program continues to address important scientific questions in southwestern U.S. including continental accretionary tectonics, the mechanics of crustal extension and compression, modes of deformation in the seismogenic regions of southwestern U.S., the structure of batholiths, and basement tectonics of the petroliferous basins of coastal California. CALCRUST seeks to carry structural relationships from the outcrop to depth in seismic sections, and also hopes to investigate techniques by which subsurface reflection data can be related directly to subsurface rheology and petrochemistry, such as through the use of shear waves and seismic velocity analysis. The CALCRUST activities during the award period will consist of data processing and subsequent analysis of existing data sets and participation (with USGS and Stanford) in a pilot study to image the crustal structure and active faults of the San Francisco Bay area.
