Abstract

This work is dedicated to gas-bearing empty ice crystallites 100–500 μm in size, which were found for the first time in Paleogene diatomic clay in the upper part of the frozen sequence of Western Siberia. The spherical, caselike, and splintered crystallites with hexagonal and curved faces are not related to relict gas hydrates and are the results of shift deformations of plastic frozen clayey deposits under degassing of the above Cenomannian rocks. These data should be taken into account in modeling the fluid dynamics and geodynamics of the frozen sequences, including the shallow shelf of the Arctic seas.
