COLLABORATIVE RESEARCH: KRISP 88-89: Kenya International Seismic Project - An International Cooperative Experiment

最近关于大陆裂谷起源和发展的研究显然因我们缺乏对东非裂谷深层结构的了解而受到阻碍。这一经典的裂痕是衡量所有其他裂痕的标准。这笔赠款是支持美国参与一项国际努力的五项合作赠款之一，该国际努力旨在对这一裂痕的肯尼亚部分进行合作研究。主要资金由德意志联邦共和国和欧洲经济共同体提供，法国、荷兰、西班牙和爱尔兰以及肯尼亚也参与其中。美国地质调查局也发挥了重要作用，将提供大量的野外仪器。1985年完成了初步实验。这项实验的结果表明，肯尼亚裂谷的深层结构与预期不同，该项目的主要阶段在科学上是有效的，在后勤上也是可行的。主要的地震实验旨在确定裂谷和邻近地区的岩石圈结构。沿裂谷的次莫霍面岩石圈的结构，裂谷轴线区域的详细结构，以及裂谷与邻近地区之间的过渡带是重点区域。

Recent studies on the origin and development of continental rifts have clearly been hampered by our lack of knowledge on the deep structure of the East African Rift. This classic rift is the standard by which all others are measured. This grant is one of five collaborative grants which support U.S. participation in an international effort to conduct a cooperative study of the Kenyan portion of this rift. Major funding is being provided by the Federal Republic of Germany and the European Economic Community, with additional participation by France, Holland, Spain and Ireland, as well as Kenya. The U.S. Geological Survey also has a major role, and will provide a large number of field instruments. A preliminary experiment was completed in 1985. The results of this experiment suggest that the deep structure of the Kenya Rift is different than anticipated and that the major phase of the project is both scientifically valid and logistically feasible. The major seismic experiment is aimed at determining lithospheric structure in the rift and in adjacent areas. Structure of the sub-Moho lithosphere along the rift, detailed structure in the axial area of the rift, and the transition zones between the rift and adjacent areas are the prime areas of emphasis.
