| Research Abstract |
For the measurement of energy within the crystal fragments, I have developed the capsule using in hydrofluoric acid. This capsule is the first in the world.
I have succeed in measurement of the heat of dissolution of quartz by using a microcalorimeter. On the bases of the heat of dissolution of amorphous SiO2, The heat of dissolution was about 2000J/g. The joule heat correspond with 1011 erg. On the basis of above menstion, energy partitioning during seismic slip is considered to be three types of energy as fracture surface energy, frictional heat energy and seismic wave energy and main consumptive energy is frictional heat and seismic wave energy, however, our results of the study shows that most consumption of fracture energy is the energy of the amorphization of crystal by the mechanical energy. This is new evidence and contribution for material seismology.
