中文摘要
红海北部是一个独特的地区,目前正在经历从大陆裂谷到海洋海底扩张的转变。最近的工作使人们对该区域的结构框架有了一般的了解;然而,对该框架的解释仍然存在基本分歧,特别是海洋地壳的可能存在和分布存在争议。因此,首席研究员从25 - 26 n之间的关键区域进行了全面的、迄今为止专有的地球物理调查,从中寻找并获得了地球物理数据。对这些数据的研究将使争议得到直接解决,并使红海演变的各种模型所作的预测能够在一个地区得到检验地球物理和地质框架目前尚不清楚。
英文摘要
The northern Red Sea is a unique region that is presently underdoing the transition from continental rifting to oceanic seafloor spreading. Recent work has led to a general understanding of the structural framework of the region; however, there is still a basic disagreement over the interpretation of that framework, and, in particular the possible presence and distribution of oceanic crust is disputed. The principal investigator therefore sought out and obtained access to the geophysical data from a comprehensive and hitherto proprietary geophysical survey of the critical area between 25 & 26 N. Study of this data will allow the controversy to be directly addressed and will allow predictions made by the various models for the evolution of the Red Sea to be tested in an area where the geophysical and geological framework is presently not known.
