Why this differs from similar rows?
Comparison value cited from Frost and Fei (1999) for Mg-endmember phase D; sibling row cites a different original study (Hushur et al. 2011) with a different K_T0.

Evidence from the paper
The isothermal bulk modulus of our Al-bearing phase D is much lower than that of Mg-endmember phase D: K_T0 = 166 (3) GPa from Frost and Fei (1999)
