Our project strives for a quantitative understanding of earth processes related to incipient continentcontinent collision, exemplified on the instance of Cyprus and the Eratosthenes Seamount (ESM) in the eastern Mediterranean where collision was initiated in the early Pleistocene. The 3D-geometry of the down thrusted crustal block of the seamount will be examined for the first time by the integrated interpretation of refraction, gravity, magnetic, magneto-telluric and multi-channel seismic data. The 2D-geometry of the uplifted and overriding Cyprus-Anatolian plate will be unravelled by the analysis of an amphibian refraction seismic profile. High-resolution reflection seismic, echosounder and multi-beam data represent the key for the in-depth understanding of the impact of the structural shortening on the stratigraphy, salt tectonics, slope stability and fluid migration of the interjacent sedimentary succession. All necessary data have been already collected in spring 2010 during more than 3 months of marine surveying and along a 650 km long refraction land seismic profile across Cyprus and southern Turkey. The outcome of this project will represent essential constraints for subsequent quantitative earth process modelling.

我们的项目致力于定量了解与早期大陆碰撞相关的地球过程，以塞浦路斯和地中海东部的埃拉托色尼海山 (ESM) 为例，碰撞在更新世早期开始。将首次通过折射、重力、磁力、大地电磁和多道地震数据的综合解释来检查海山下冲地壳块的 3D 几何形状。通过对两栖折射地震剖面的分析，将揭示隆起并压倒的塞浦路斯-安纳托利亚板块的二维几何结构。高分辨率反射地震、回声测深和多波束数据是深入了解构造缩短对相邻沉积层序地层、盐构造、边坡稳定性和流体运移影响的关键。 2010 年春季，经过 3 个多月的海洋勘测以及跨越塞浦路斯和土耳其南部 650 公里长的折射陆地地震剖面，所有必要的数据均已收集完毕。该项目的结果将代表后续定量地球过程建模的基本约束。
