The combination of carbon-bearing compounds in the kimberlite pipes may be divided into distinct geochemical groups, genetically associated with exogenic or endogenic geological processes. In analyzing the isotope composition of diamonds from eclogite and kimberlite, graphite in concentrated form from eclogite and ultrabasic inclusions in kimberlite, and postmagmaic carbonic acid from the matrix of kimberlite, it was established that these compounds have a distinctive endogenic nature. The isotope composition of the limestones of marine origin has been determined by the isotope-exchange reation /sup 13/CO/sub 2/ (gas) + /sup 12/CO/sub 3/ (solution) reverse arrow..-->.. /sup 12/CO/sub 2/ (gas) + /sup 13/CO/sub 3/ (solution), which is rigidly associated with temperature of sedimentation and has controlled the ''heavy'' isotope composition of these rocks. The isotope composition of the bitumens has not yet enabled us to resolve the problem of the origin of the bitumen shows (biogenic or abiogenic). However, the similarity of the isotope composition of bitumens examined from various bitumen shows indicates identical thermodynamic conditions of formation.
