Abstract

<p>In this study, we separated global burial rate of organic carbon into terrestrial and marine environments, using compiled data of organic carbon and pyrite sulfur (C/S) ratio from sediments deposited in oxygenated seawater and freshwater environments. As a result, it is indicated that the organic burial in terrestrial environment appeared for the first time from Silurian to Devonian, when first forests were formed after the emergence of vascular plants. Burial rate of organic carbon in terrestrial environment increased a lot in the Late Carboniferous and the Early Permian, when a lot of coal was produced. At Frasnian/Famennian (F/F) and Permian/Triassic (P/T) mass extinction boundaries, burial rate of organic carbon in terrestrial environment has decreased significantly, while that in marine environment has increased during long term, global scale Ocean Anoxic Events (OAEs).</p>
