Abstract

The Menilite Beds (Carpathian Flysch Belt) contrast with the Tard Clay (Hungarian Paleogene Basin) and are characterized by a high rate of sedimentation and biogenic silica enrichment. The Menilite Beds are believed to have been deposited under sulphidic bottom water, while the existence of a sulphidic water at the bottom of the "Tard Sea' cannot be documented. C/S relationships, organic maturity data, and knowledge of anaerobic bacterial processes, especially the mechanisms and extent of the early diagenetic escape of reduced sulphur from recent sediments. permit assessment of the rates of organic carbon deposition. The obtained values of 10.8 t m-2 Ma-1 for the Menilite Beds and 1.4-1.8 t m-2 Ma-1 for the Tard Clay fit reasonably with geological settings. -from Authors
