Abstract
Garnet is one of the major minerals down to the top of lower mantle approximately 660 km with spinel and pyroxenes. Garnet transforms into perovskite and corundum in the lower mantle, however its sequence is still in controversy. We measured the compressibility of a natural almandine at high-pressure up to 62 CPa using Mao-Bell type diamond anvil cell (DAC) at room temperature. Chemical formula of the specimen is ($Fe_{2.52}Ca_{0.21}Mg_{0.18}Mn_{0.12})Al_{2.23}Si_{2.97}O_{12}$. Results of this compression study are as follows: a : $10.175\;{\AA}$, V : $1251.16\;{\AA}^{3}$, $D_{x}$ : $5.265\;g/cm^{3}$ at 62 GPa; bulk modulus is 156 GPa using Birch-Murnaghan equation of state (EoS) with a fixed $K_{0}\; of 4. This study would be the first time attempt accomplished with the high pressure DAC using synchrotron radiation at the Pohang Light Source (PLS) in Korea.
