A relationship between phonon conductivity and seismic parameter Φ for silicate minerals
Tóm tắt
The relationship between the phonon conductivity at room temperature (K
N
) and the seismic parameter (Φ) for silicate minerals is suggested. The considerations are based on the Debye model of thermal energy transport phenomena in solids and on the ‘seismic equation of state’ for silicates and oxides given byAnderson (1967). The semiempirical relationship is the formK
N
= 0.43Φ0.82 where Φ is in km2/s2 andK
N
in mcal/cm s K, and the empirical relationship isK
N
=(0.528±0.006)Φ −(8.18±2.11). The laboratory data on thermal and elastic properties for several silicates were taken fromHorai andSimmons (1970).
