organic matter

The organic matter of rock phosphate has been the subject of numerous studies. The valuation and resolu-tion of some problems, such as fouling, encountered in the industrial production of phosphoric acid are of great interest, and enable better production yields of phosphoric acid. The solid deposits formed in the production of wet process phosphoric acid were characterized and revealed the malladrite, gypsum, trace metals, and the presence of organic matter. The identification of the organic matter was carried out in the fouling samples using FT-IR and Raman spectroscopies.

Purpose. The objective of this study was to investigate the depositional environments of organic-rich Ediacaran and Silurian strata on the south-western slope of the East-European platform. In particular, the factors facilitating the efficient fossilization of organic matter in marine sediments and which play the key role in black shales formation, are the basic elements of petroleum systems being considered.
