S Reflector and Rifting Processes: Galicia Bank Basin and Iberia Abyssal Plain

目前正在提供资金，使私人投资机构能够继续解释1997年游轮前往加利西亚海岸和伊比利亚深海平原期间收集的地震反射和折射数据。收集了大约4000公里的高质量反射剖面，部署了56个OBS和水听器，在这些剖面上已经完成了基本处理。除了这些数据外，英国和法国在该地区的数据也将构成综合的一部分。PI将进行叠前深度偏移，以成像上地幔隆起形成的橄榄岩脊的内部结构。还计划估算伊比利亚边缘地壳伸展的横向变异性，计算剩余Buguer重力异常，并与共轭的新福克兰边缘进行比较。

Funds are being provided to allow the PIs to continue the interpretation of the seismic reflection and refraction data gathered during a 1997 cruise to the Galicia Bank and the Iberian Abyssal Plain. Some 4000 km of high-quality reflection profiles with 56 deployed OBS and hydrophones were collected on which the basic processing has been completed. In addition to this data, the British and French data in teh region will also form a part of the synthesis. The PIs will pursue pre-stack depth migration to image the internal structure of the peridorite ridge formed by the uplift of the upper mantle. Extimation of lateral variability of crustal extension on Iberian margin, calculation of residual Buguer gravity anomaly and a comparison with the conjugate New foundland margin are also planned.
