Smirnov, M. B. | Poludetkina, E. N.
A procedure is proposed for estimating the content of individual groups of compounds, anoxia markers, in the photic layer of the sedimentation basin and their total content in fractions of oils and dispersed organic matter. Appropriate variants of data presentation are analyzed. Based on the data on the common content of anoxia markers, a method has been proposed for answering the question of whether hydrogen sulfide contamination was permanent, covering the major part of the water column, or there was an episodic infection spread to a limited water layer. These data also allow the assessment of the role of organic matter formed under anoxic conditions in its total balance. A composition parameter is proposed that ensures the determination of the similarities in the conditions of organic matter transformation in different rocks.
