| Summary: | Detailed seismoacoustic investigation has been carried out in the southern part of Lake Bol’shoe Yarovoe (Altai Krai) to map the bottom sediments and features associated with the presence of gas. The obtained results demonstrate that various types of gas can be differentiated in the lake, such as pockmarks, acoustic turbidity, and gas flares. These features, on the one hand, prevent the reconstruction of sequence stratigraphic patterns and, on the other hand, contribute to understanding of the processes of gas formation and migration in the sediments, possible impacts of these processes on the formation of sediments enriched in the organic matter, as well as help to recognize these processes in the ancient sediments. In this regard, the problems arising from the use of such sediments for paleogeophysical reconstructions have been shown. The paper points out the importance of studying the formation of methane in the sediments of lakes, because it plays an important role in the climate change. |
