Outline of Final Research Achievements |
Rapid heating experiments of natural rock were conducted in order to quantify the mechanism of "Co-seismic chemical reaction" induced by frictional heat generation during faulting. As a typical reactant, thermal maturation of coal was focused on in this research. Vitrinite reflectance values (%Ro) were measured for whole volume of the samples after the rapid heating experiments. As the results, values of %Ro showed wide variation in each sample compared with that of isothermal experiments and numerical analyses based on chemical kinetic equation. This might not be caused only by heterogeneity of thermal properties of samples, but also by hydraulic characteristics such as permeability, which controls degassing speed.
