本文应用岩石和古地磁方法研究了塔曼半岛的亚速海岸的图兹拉剖面上半部分的陆相沉积物，其年代为50-10 ka。在这项研究中获得的地磁场的角度分量的详细曲线显示出一个异常方向与在Roxolany部分（乌克兰）的岩石中发现的异常层位在时间上（25-35 ka）一致。根据地磁漂移的世界时标，异常方向与莫诺湖漂移相关。在50-10 ka时间段内，NRM0.015/SIRM（图兹拉剖面）和NRM 250/KB（罗克索拉尼剖面）与世界合成曲线VADM-21和Sint-800之间的显著相关性表明，在该时间段内，曲线NRM0.015/SIRM反映了地磁场相对古强度的变化。
Petro-and paleomagnetic methods are applied to the study of the upper part of the Late Pleistocene Tuzla section (Azov coast of the Taman Peninsula) composed of continental sediments and dated at 50–10 ka. The detailed curves of the angular components of the geomagnetic field obtained in this study display an anomalous direction coinciding in time (∼25–35 ka) with an anomalous horizon discovered in rocks of the Roxolany section (Ukraine). According to the world time scale of geomagnetic excursions, the anomalous direction correlates with the Mono Lake excursion. A significant correlation between the time series NRM0.015/SIRM (Tuzla section) and NRM250/KB (Roxolany section) in the interval 50–10 ka and the world composite curves VADM-21 and Sint-800 implies that, in this time interval, the curve NRM0.015/SIRM reflects the variation in the relative paleointensity of the geomagnetic field.
