英文摘要	Using a diamond-anvil cell and synchrotron X-ray diffraction, the compressional behavior of a synthetic qandilite Mg2.00(1)Ti1.00(1)O4 has been investigated up to about 14.9 GPa at 300 K. The pressure-volume data fitted to the third-order Birch-Murnaghan equation of state yield an isothermal bulk modulus (K-T0) of 175(5) GPa, with its first derivative K'(T0) attaining 3.5(7). If K'(T0) is fixed as 4, the K-T0 value is 172(1) GPa. This value is substantially larger than the value of the adiabatic bulk modulus (K-S0) previously determined by an ultrasonic pulse echo method (152(7) GPa; Liebermann et al. in Geophys J Int 50:553-586, 1977), but in general agreement with the K-T0 empirically estimated on the basis of crystal chemical systematics (169 GPa; Hazen and Yang in Am Miner 84:1956-1960, 1999). Compared to the K-T0 values of the ulvospinel (Fe2TiO4; similar to 148(4) GPa with K'(T0) = 4) and the ringwoodite solid solutions along the Mg2SiO4-Fe2SiO4 join, our finding suggests that the substitution of Mg2+ for Fe2+ on the T sites of the 4-2 spinels can have more significant effect on the K-T0 than that on the M sites.; National Science Foundation-Earth Sciences [EAR-1128799]; Department of Energy-GeoSciences [DE-FG02-94ER14466]; COMPRES under NSF [EAR 11-57758]; GSECARS through NSF [EAR-1128799]; GSECARS through DOE [DE-FG02-94ER14466]; DOE Office of Science by Argonne National Laboratory [DE-AC02-06CH11357]; Natural Science Foundation of China [41440015, 41273072]; SCI(E); EI; ARTICLE; xi.liu@pku.edu.cn; 4; 301-306; 43
