Physical properties, structural features, and climate signals in lake sediments of the ICDP site Lake Van (Turkey) derived from downhole logging

在ICDP项目Paleo货车的框架内，将在货车湖（土耳其）进行几次深度达240米的钻探。该项目旨在研究敏感的半干旱地区的环境和气候变化。这些钻孔的大量地球物理井下测井为回答本项目范围内的问题提供了基础。解释井下测井数据允许建立一个完整的岩性测井，描述钻探沉积物的岩石物理特征，确定沉积结构，并获得有关古气候条件的证据，在长达500万年。钻孔中的地震实验可以将详细的地质信息与船载地震剖面联系起来。因此，当地的结果可以转化为空间信息提供了一个重要的贡献的沉积模式和构造结构的湖货车盆地的理解。

In the framework of the ICDP project PaleoVan several up to 240 m deep drillings will be carried out at Lake Van (Turkey). The project aims at studying environmental and climate variations in a sensitive semiarid region. Extensive geophysical downhole logging of these boreholes delivers a basis for answering questions in the scope of this project. Interpreting the downhole logging data permits to establish a complete lithological log, to characterize the drilled sediments petrophysically, to determine sedimentary structures and to obtain evidences about palaeoclimatic conditions during up to 500 ka. Seismic experiments in the borehole allow linking the detailed geological information with shipborne seismic sections. Thus, local results can be transformed into spatial information providing an important contribution to the understanding of the sedimentological patterns and the tectonic structure of the Lake Van Basin.
