Neotectonic evolution of the island of Rhodes (Greece) during the Pleistocene: an integrated micropaleontological and structural geology approach (NERHO)

罗德斯岛(地中海东部)位于非洲板块和欧亚板块的碰撞带，含有丰富的微化石沉积档案，因此提供了根据微化石组合重建岛上由构造引起的过去垂直运动的机会。我们特别建议研究该岛在更新世和近期的新构造演化，以更好地了解地中海东部地区正在进行的板块汇聚过程中的长期和短期构造事件。为了达到我们的目标，我们计划应用一种结合微古生物学和构造地质学方法的跨学科方法，并将进一步使用一套统计和年代地层学方法。更全面地了解该岛在早至中更新世期间的区域新构造演化是至关重要的，因为罗兹东海岸的不同沉积沉积中心可能独立地经历了垂直运动。这些沉积中心详细的定量古水深重建，修正了进动驱动的营养条件变化以及冰川稳定效应，将使我们能够准确估计过去局部垂直运动的速率。这些估计将进行(1)相互比较，(2)与以目前海平面为参考水平的一级构造不连续的遥感和野外运动学分析得出的新构造地壳形变运动学进行比较。通过我们的综合方法，我们将对罗得岛的整体空间和时间新构造动力学产生新的见解，从而为验证区域俯冲模型和更好地了解东地中海地区的现代俯冲过程提供相关的基线数据。

The Island of Rhodes (eastern Mediterranean Sea) is situated at the collision zone between the African and Eurasian plates and contains microfossil-rich sedimentary archives, thus, provides the opportunity to reconstruct tectonically-induced past vertical motions of the island based on microfossil assemblages. We specifically propose to study the neotectonic evolution of the island during the Pleistocene and in recent times to better understand long-term and short-term tectonic events during ongoing plate convergence in the eastern Mediterranean region. To reach our aims, we plan to apply an interdisciplinary approach combining micropaleontological and structural geological methods and will further use a set of statistical and chronostratigraphic methods. A more comprehensive view on the regional neotectonic evolution of the island during the early to mid-Pleistocene is crucial since the different sedimentary depocenters along the east coast of Rhodes may have independently undergone vertical motions. Detailed quantitative paleo-water depth reconstructions in these depocenters, corrected for precession-driven changes in trophic conditions as well as glacio-eustatic effects, will allow us to accurately estimate rates of past local vertical motions. These estimates will be compared (1) to each other and (2) to neotectonic crustal deformation kinematics derived from remote sensing and field-based kinematic analyses of first-order structural discontinuities by using the present sea level as reference level. With our integrated approach we will bring new insights into the overall spatial and temporal neotectonic dynamics of Rhodes, and thus will provide relevant baseline data for the validation of regional subduction models and to better understand modern subduction processes in the Eastern Mediterranean Sea region.
