Abstract
Comparative study of genesis and structure of dispersed organic matter (DOM) from background pelagic bottom sediments and sediments inside an active hydrothermal field Ashadze-1 collected during the cruise of the R/V “Professor Logachev” in 2003 was carried out. The received results allow to speak about an essential originality of structure and distribution of DOM in bottom sediments of the field Ashadze-1, according to unique physical and chemical conditions and facial specificity of sedimentation in hydrothermal zones. At the same time, attributes of petroleum hydrocarbons abiogenic synthesis hasn’t been fixed. Opposite, the received data allow to consider the process of fast maturing of biogenic OM in hydrothermal systems as a major factor of HC formation.
