Abstract
In the section of the eastern Black Sea basin and the Caucasus continental slope, according to 3D seismic data, unique objects were first discovered and described — vertical failure in the Upper Cretaceous — Lower Miocene deposits. An interesting feature of these structures is a close to isometric shape in plan. About 40 objects have been identified on an area of more than 1000 m2. «Bulls-eye» («multiphase») paleo-pockmarks [Andresen, Huuse, 2011], as well as karst collapse [Zuo et al., 2009] are proposed as world analogues with a similar wave pattern on seismic data. The corresponding genesis models are considered, but none of the theories allows drawing a conclusion. The discovered objects are unique and require further investigation.
