Abstract

Unique vertical subsidence structures in Upper Cretaceous–Lower Miocene deposits were discovered and described in a section of the eastern Black Sea basin and the Caucasus continental slope, according to 3D seismic data. One interesting feature of these structures is a shape that is close to isometric on a map. Approximately 40 objects have been identified in an area of more than 1000 m². “Bulls-eye” (“multiphase”) paleo-pockmarks (Andresen and Huuse, 2011), and karst collapse (Zuo et al., 2009) are proposed as analogues with similar wave patterns. The corresponding genesis models are considered, but none of the theories allows definite conclusions to be drawn. The discovered objects are unique and require further investigation.

使用3D地震数据发现的东部黑海横截面中的独特对象

摘要

根据3D地震数据，在黑海东部盆地和高加索大陆坡的一部分中发现并描述了上白垩统-下中新世沉积物中独特的垂直沉降结构。这些结构的一个有趣特征是形状接近地图上的等轴测图。在面积超过1000 m ²的区域中已发现约40个物体。提出了“牛眼”（“多相”）古麻点（Andresen和Huuse，2011）和岩溶塌陷（Zuo等，2009）作为类似波型的类似物。考虑了相应的起源模型，但是没有一种理论可以得出明确的结论。发现的对象是唯一的，需要进一步调查。
