强有力的年龄-深度模型对于发展复杂的湖盆沉积历史解释是必不可少的。在大多数情况下，这些模型是使用综合地球科学方法建立的，包括生物地层学、磁性地层学和放射性测年法。在这项研究中，我们提出了一种方法来构建年龄-深度模型的基础上整合井下测井和地震勘探数据时，没有样品可用于定年。使用奥赫里德湖（北马其顿/阿尔巴尼亚）的数据显示了这种方法的一个例子。首先，我们解释了地震数据，并将三个站点- DEEP，Pestani和Cerava -的井下测井数据与LR 04海底叠加。我们使用旋回地层学方法交叉检查由此产生的年龄-深度模型，该方法提供了相同数量级的沉积速率。所调查的沉积物的最大年龄是基于湖相地震标志层，在DEEP/Pestani约为100万年，在Cerava约为60万年。在第二步中，我们使用沉积物的物理性质，构建了基于聚类分析的人工岩性测井，并将其与年龄-深度模型相结合。这使得在Cerava和Pestani.Our方法的沉积学历史的初步解释不能替代经典的沉积物岩心调查，但我们建议，这两个步骤的方法被应用到未来的国际大陆科学钻探计划的项目。它可以迅速提供关于年龄和沉积物类型的初步结果，在没有可确定年代的材料时特别有用。
Robust age-depth models are essential for developing sophisticated interpretations of the sedimentological history in lake basins. In most cases, such models are created using an integrated geoscientific approach, including biostratigraphy, magnetostratigraphy and radiometric dating. In this study, we present an approach to construct age-depth models based on integrating downhole logging and seismic survey data when there are no samples available for dating. An example of this method is shown using data from Lake Ohrid (North Macedonia/Albania).First, we interpret seismic data and correlate downhole logging data from three sites - DEEP, Pestani and Cerava - to the LR04 benthic stack. We cross-check the resulting age-depth models using cyclostratigraphic methods, which deliver sedimentation rates that are on the same order of magnitude. The maximum age of the investigated sediments is based on lacustrine seismic marker horizons and is approximately 1 million years at DEEP/Pestani and 0.6 million years at Cerava.In the second step, we construct an artificial lithological log based on cluster analysis using the physical properties of the sediments and integrate it with the age-depth model. This allows an initial interpretation of the sedimentological history at Cerava and Pestani.Our methodological approach cannot substitute classical sediment core investigations, but we suggest that this two-step approach be applied to future projects of the International Continental Scientific Drilling Program. It can rapidly provide preliminary results on age and sediment type and is particularly useful when datable material is not available.
