Stratigraphy and tectonic overprint of carbonate and drift deposits in the south-western Mediterranean STRATEC (M69/1)

本项目的最终目标是：1)在Alboran Ridge、Oran Bay和Mallorca西南部的几乎无硅质碎屑环境中建立晚第四纪碳酸盐岩沉积的地震地层格架；2)在所有工作区域的漂移沉积基础上重建流行的和古老的海洋环境。3)研究Mallorca西南地区晚中新世碳酸盐岩的天然气圈闭和上新世-第四纪覆盖层的运移路径。4)分析Bolonia Bay、Alboran Ridge南北和Oran外海的新构造活动，从断裂模式和块体消耗方面揭示其对沉积演替的影响。这将通过2006年9月M69/1号（西地中海）巡航期间收集的地震和水声数据解释来实现。地震数据由高度复杂的144通道数字拖缆系统记录。在第一阶段，工作计划的目标是处理和解释。为了优化成像，将采用crs叠加、nip层析成像和叠前深度偏移等先进的处理方法。口译将以2D和3D形式进行。

The final goals of this project are: 1) To establish a seismo-stratigraphic framework for Late- Quaternary carbonate deposits in the almost siliciclastic free settings at the Alboran Ridge, Oran Bay, and south-western Mallorca. 2) To reconstruct the prevailing and ancient oceanographic setting on the basis of drift deposits in all working areas. 3) To investigate gas traps in Late-Miocene carbonates and migration paths into the Pliocene-Quaternary overburden south-west of Mallorca. 4) To analyze neotectonic activity off Bolonia Bay, north and south of the Alboran Ridge, and off Oran in order to unravel its impact on the sedimentary succession in terms of fault pattern and mass wasting. This will be achieved by means of seismic and hydroacoustic data Interpretation collected during the cruise M69/1 (Western Mediterranean Sea) in September 2006. The seismic data have been recorded by a highly sophisticated 144-channel digital streamer System. During the first period the working program aims on the processing and Interpretation. Advanced processing methods like CRS-stacking, NIP-tomography and pre-stack depth migration will be applied in order to optimize the imaging. The Interpretation will be carried out in 2D and 3D.
