Bündelantrag SCOPSCO: Scientific Collaboration on Past Speciation Conditions in Lake Ohrid - Physical properties, structural features, and climate signals derived from downhole logging

该项目是德国几家研究机构DFG捆绑提案的核心部分，并被整合到一个合作研究计划中，主要是与欧洲研究机构的合作伙伴。在国际综合合作项目“过去形态条件科学合作”项目的框架内，将在奥赫里德湖（阿尔巴尼亚和马其顿）进行5次20米至680米深的钻探。该项目旨在研究奥赫里德湖的年龄和起源，获取有关晚第三纪/第四纪地质、环境和气候变化的信息，并确定生物发展的驱动力。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。解释井下测井数据可以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，并获得有关过去三到五百万年的古气候条件的证据。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奥赫里德湖的构造结构的理解。

The proposed project is the central part of a DFG bundle proposal of several German research institutions and is integrated in a collaborative research program, mainly with partners from European research institutions. In the framework of the ICDP project Scientific Collaboration On Past Speciation Conditions (SCOPSCO) five 20 m to 680 m deep drillings will be carried out at Lake Ohrid (Albania and Macedonia). The project aims to study age and origin of Lake Ohrid, to achieve information about geological, environmental and climate variations of Late Tertiary/Quaternary age and to determine the driving forces of the biotic development. 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 likely during the last three to five million years. 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 Lake Ohrid.
