Abstract
The authors have studied the change in the component composition of wollastonite marble from Slyudyanka deposits at increasing pressure (p
= 0.1-12000 MPa) and temperature (T = 300-6000 K). Metamorphism of marble maturation has been found. The essence
of maturation is the calcite melting, carbon dioxide deposition, the monolith compaction, the transformation
of mineral composition at pressure increase up to the value of the initial
components. When the pressure value reaches 12000 MPa the original components
are reproduced, and the maturation of marble completes. Thermodynamic analysis
reveals the secrets of the marble origin.
