This award provides support for a workshop to formulate a plan of research to study terrane accretion in southeast Alaska and adjacent portions of British Columbia. Geologists and geochemists who have extensive experience in the region will be brought together with geophysicists who have expertise imaging features in the deep crust. Because of the network of water ways in southeast Alaska, it will be possible to exploit the logistic and scientific advantages of using offshore/onshore seismic imaging techniques. The geological community has a good working understanding of the distribution of rock types in the area and models for their formation and evolution. What is now needed are constraints on the nature and distribution of structures and lithologies to the base of the crust and into the upper mantle. At the workshop, the overall tectonic history of the region will be presented, followed by discussions leading to a determination of what geophysical techniques could be used to resolve the major questions and where they could best be applied.

该奖项为一个研讨会提供支持，以制定研究计划，研究阿拉斯加东南部和不列颠哥伦比亚省邻近地区的地体增长。在该地区拥有丰富经验的地质学家和地球化学家将与拥有深部地壳成像特征专长的地球物理学家聚集在一起。由于阿拉斯加东南部的水路网络，将有可能利用海上/陆上地震成像技术的后勤和科学优势。地质界对该地区岩石类型的分布及其形成和演化模式有很好的工作了解。现在需要的是对地壳底部和上地幔的构造和岩性的性质和分布进行限制。在讲习班上，将介绍该区域的总体构造历史，然后进行讨论，以确定可以使用哪些地球物理技术来解决主要问题，以及在哪里可以最好地应用这些技术。
