CALCRUST: A Regional Study of Crustal Structure and Evolution

该奖项为加州地壳研究联合会(CALCRUST)的活动持续一年提供资金。CALCRUST是由来自加利福尼亚州的地区性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为拥有从地质学到反射地震学和地震数据处理等专业知识的多方面地壳研究小组提供了共同的重点。CALCRUST科学计划正在解决有关大陆增长构造、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、深部岩石结构以及加州沿海含油气盆地的基底构造等重要问题。一个重要的焦点是低角度结构--它们在地下的几何形状和连续性。CALCRUST试图将我们对地表地质的合理完整的理解扩展到第三维度，并开始建立美国西南部表面上不同的地质地体之间的关系。在本奖项期间，重点将是完成手头数据的分析和解释，对捐赠的行业数据和根据CALCRUST合同收集的数据进行再处理，并公布结果。

This award provides funds to continue CALCRUST (California Consortium for Crustal Studies) activities for one year. CALCRUST is a regional consortium of earth scientists from California with a common interest in crustal structure and evolution. CALCRUST provides a common focus for a multifaceted, crustal-studies team with expertise ranging from geology to reflection seismology and seismic data processing. The CALCRUST scientific program is addressing important questions regarding 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. An important focus is on low-angle structures -- their geometry and continuity in the subsurface. CALCRUST seeks to extend to the third dimension our reasonably complete understanding of the surface geology, and begin the process of establishing relationships between the apparent diversity of geologic terranes in southwestern U.S. During the period of this award, the focus will be on completing the analysis and interpretation of data in hand, both the reprocessing of donated industry data and data gathered under CALCRUST contract, and the publication of results.
