The Holocene neritic carbonates of Western Mediterranean Sea

西地中海全新世浅海碳酸盐岩

基本信息

项目摘要

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.
本研究的目的是提出冷水碳酸盐的关键模型,并记录这些系统的反应全新世古气候和海平面变化。这将通过对M69/1号(西地中海)航行期间采集的样本和地球物理数据进行跨学科分析来实现。根据沉积物结构和成分,以及宏观古生物学,相将被定义和相分带的时间变化将被显示。绘制准声波剖面的厚度变化和沉积物几何形状将有助于建立层序地层模型。将沉积学和地球物理学数据联系起来,并使用绝对14 C年龄数据,将首次有可能产生地中海全新世冷水碳酸盐序列的模型。对有孔虫动物群的分析以及对浮游生物和底栖生物稳定同位素记录的生成,将提供关于气候和海洋变化对浅海碳酸盐生态系统影响的信息,并将使这些信号与深海记录相比较。根据最近的分布模式,将生成传递函数,并将其应用于沉积岩芯,以进行定量古水深重建。将这些数据与层序地层学和碳酸盐岩相数据联系起来,我们将能够将冰后期海平面上升的影响与区域新构造和沉积过程分开。
