It is found that allochthonous organic material of the hydrocarbon nature changes physicochemical properties of the bottom sediments. At the same time bitumoids of different character are formed. Oils (up to 70%) and benzene resins (up to 24%) make up the basis of the reduced A bitumoid. Their content in the oxidized С bitumoid is three or four times as low. A number of aromatic and methane-naphthene hydrocarbons in A bitumoid is 1 or 2 order as high as that in С bitumoid. In this case naphthenes predominate in the composition of methane-naphthene compounds of A bitumoid. They also exist in С bitumoid, but in considerably smaller number.Изучение свободного восстановленного битумоида А и связанного окисленного битумоида С донных осадков береговой зоны показало влияние аллохтонного органического вещества углеводородной природы на свойства битумоидов.ru
