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.

在国际地球科学中心项目PaleoVan的框架内，将在Van湖(土耳其)进行几次深达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。对这些钻孔进行广泛的地球物理井下记录，为回答本项目范围内的问题奠定了基础。通过对井下测井资料的解释，可以建立完整的岩性测井资料，对钻探的沉积物进行岩石物理特征分析，确定沉积构造，并获得有关500ka以来古气候条件的证据。井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，可以将局部结果转化为空间信息，为了解凡湖盆地的沉积模式和构造结构做出重要贡献。
