Relevance of the study is due to the importance of composition and maturity of the dispersed organic matter (DOM)
as indicators of rock forming conditions, which may contribute to the paleoecological reconstruction of sedimentation
conditions for rocks in the ore-bearing stratum of the Safyanovskoe deposit.
Objective: to analyze the composition and characteristics of DOM in carbon-siliceous rocks of the ore-bearing
stratum of the Safyanovsky copper-pyrite deposit. The obtained characteristics of the DOM make it possible to reveal
the source of original accumulation and the level of its transformation under the influence of various geological
processes. Conclusions. DOM of carbon-siliceous rocks of the Safyanovsky deposit is genetically the same, its type is mainly
sapropelic and accumulation is associated with marine conditions. A characteristic feature is, on the one hand, its
high polymerization, which is typical for DOM of the stage of late mesocatagenesis, and, on the other hand, its
molecular composition does not allow us to talk about the maturation of DOM in the process of natural regional
metamorphism.
