The Holocene neritic carbonates of Western Mediterranean Sea

本研究的目的是建立冷水碳酸盐的关键模型，并记录这些系统对全新世古气候和海平面变化的反应。这将通过对M69/1（西地中海）巡航期间恢复的样品和地球物理数据进行跨学科分析来实现。根据沉积物的质地和组成，结合宏观古生物学，对渐变进行定义，并显示渐变带的时间变化。在副声波剖面中绘制厚度变化和沉积物几何图形将有助于建立层序地层模型。将沉积学和地球物理数据结合起来，并使用绝对的14C年龄日期，这将是第一次有可能产生一个全新世地中海冷水碳酸盐序列模型。对有孔虫动物群的分析以及浮游生物和底栖生物稳定同位素记录的生成将提供有关气候和海洋学变化对浅海碳酸盐生态系统影响的信息，并将这些信号与深海记录进行比较。根据最近的分布模式，生成传递函数，并应用于沉积物岩心进行定量古水深重建。将这些数据与层序地层学和碳酸盐相数据相结合，我们将能够将冰川后海平面上升的影响与区域新构造和沉积作用分离开来。

The objective of this study is to present key models for cool-water carbonates, and to document the reaction of these systems to Holocene paleoclimatic and sea-level change. This will be achieved through an interdisciplinary analysis of samples and geophysical data recovered during the cruise M69/1 (Western Mediterranean Sea). Based on sediment texture and composition, as well as macropaleontology, fades will be defined and temporal changes of fades zonations will be shown. Mapping thickness variations and sediment geometries in parasound profiles will allow to establish a sequence stratigraphic model. Linking sedimentological and geophysical data, and using absolute 14C age dates, for the first time it will be possible to produce a model of the Holocene cool-water carbonate sequence in the Mediterranean Sea. Analyses of the foraminiferal faunas and generation of planktonic and benthic stable isotope records will provide information on the impact of climatic and oceanographic changes on the neritic carbonate ecosystems and will allow the comparison of these signals with the deep-sea record. Based on Recent distribution patterns, transfer functions will be generated and applied to the sediment cores for quantitative paleobathymetric reconstructions. Linking these data with sequence stratigraphy and carbonate facies data, we will be able to separate the impact of the postglacial eustatic sealevel rise from regional neotectonic and sedimentological processes.
