Abstract
Holocene Black Sea basin sediments were formed in our opinion in happened geocatastrofic event on the border Pleistocene-Holocene (8-9 thousand years ago). As a result on the Upper Pleistocene lake sediments occur organogenic-mineral (sapropel diatoms and coccolith) marine sediments. The characteristic features of happened catastrophe is the occurrence of hydrogen sulfide charging that conserved the organic matter and protect it from decomposition. Chemical composition and properties of deep-water organogenic - mineral deposits give us reason to Tip of the raw material as an integrated multi-purpose and most notably in agriculture.
