CALCRUST: A Regional Study of Crustal Structure and Evolution

该提案要求为加州地壳研究联合会明年继续开展活动提供资金。CALCRUST是一个由来自加利福尼亚各机构的地球科学家组成的联盟，他们对地壳结构和进化有共同的兴趣。CALCRUST的科学团队包括从区域地质学到反射地震学和地震数据处理的专业人员。CALCRUST项目继续解决美国西南部的重要科学问题，包括大陆吸积构造、地壳伸展和压缩力学、美国西南部震区的变形模式、基岩结构和加利福尼亚沿海含油气盆地的基底构造。CALCRUST试图在地震剖面中从露头到深处进行结构关系，并希望研究地下反射数据可以直接与地下流变学和岩石化学相关的技术，例如通过使用横波和地震速度分析。在授予期间，CALCRUST的活动将包括数据处理和对现有数据集的后续分析，并参与（与美国地质调查局和斯坦福大学一起）对旧金山湾区的地壳结构和活动断层进行成像的试点研究。

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.
