XRD graphitization degrees: a review of the published data and new calculations, correlations, and applications

A system for transformation, correlation, and unification of subordinations between d002 (Å) semi-graphite graphite, graphitization degrees metamorphic temperature was created. The existing equations in the literature were analyzed new equations, which determine correlation relationships these parameters, formulated. effect factors that control processes (temperature, general pressure tectonic stress, structure origin primary carbon matter, orientation formations, fluids, mineral chemical composition, duration processes) also considered. It concluded structural state graphite is reversible, this can be used facies diagnostics studying history graphite-bearing rocks. scale proposed.
