Owen Basin and Southeast Oman: Defining the Signature of an Ocean - Continent Transform Boundary

对西北印度洋构造史的主流解释表明，阿曼海岸是一个被动的大陆边缘，在晚侏罗世期间从印度断裂而来。最近获得的信息支持了另一种历史，包括：a)磁性数据，b)与钻孔相关的地震反射剖面，c)古深度估计，以及d)阿曼边缘观测到的变形。这些数据暗示阿曼边缘位于一条主要的转换断层上。本奖励中包括的资金将支持对这些新数据进行分析和综合，以试图确定哪个模型是正确的。了解阿曼边缘的演化对于破译印度洋的历史、印度与欧亚大陆的碰撞以及阿曼边缘的沉积历史都很重要。

Prevailing interpretations of the tectonic history of the NW Indian Ocean specify that the coast of Oman is a passive continental margin that rifted from India during the Late Jurassic. An alternative history is supported by recently acquired information comprising: a) magnetics data, b)seismic reflection profiles tied to boreholes, c) paleodepth estimates, and d) deformation observed along the Oman margin. These data imply that the Oman margin lie along a major transform fault. Funds included in the present award will support an analysis and synthesis of this new data in an attempt to determine which model is correct. Understanding the evolution of the Oman margin is important to deciphering the history of the Indian Ocean, the collision of India with Eurasia, and the history of sedimentation on the Oman margin.
