The new scenario of problem the anomalous enriching the heavy isotope of carbon of carbonates is offered at the simultaneous enriching of organic carbon an easy isotope. This scenario is based on assumption of simultaneous work of two basic isotopic effects: mass-dependent (classic kinetic), which, sends the easy isotopes of carbon in organic mass, the same enriching by them product of reaction and mass-independent (magnetic), which, assorting isotopes in obedience to their magnetic moments, accordingly abandons the magnetic isotope of 13C in an initial matter, і.e. in a carbonate. First sedimentary carbonates are examined as crystalline polymers amorphous areas of which are mikrospaces of limited and reserved volume. Radicals, being in such mikrospaces, is forced to regenerate in initial molecules, repeatedly repeating a cascade spin-selective cycle, which increases probability of isotopic separation in oftentimes, abandoning here 13C in an initial matrix, і.e. in a carbonate. Therefore many looked after cases of the anomalous (in relation to kinetic constructions) enriching of carbonates the heavy isotope of carbon, probably can be explained work of magnetic isotopic effect.
