Organic geochemistry and accumulation conditions of Nechenskoe deposits coal

Brown coals of the Nechenskoe deposit were studied by the organic geochemistry methods. It is established that the distribution of normal and isoprenoid hydrocarbons as well as polycyclic biomarkers responsible low maturity of organic matter of rocks. The original organic matter of coals studied mainly consisted of the remains of higher plants, the admixture of alga matter is negligible.
