Abstract
In this paper we investigate the possibility of storing water in the shallow martian mantle under water-saturated fluid absent conditions for different bulk silicate mars (BSM) compositions. We performed phase equilibria experiments on two BSM compositions with comparable Mg number for pressure between 2 and 4 GPa, temperatures between 950 to 1150°C, and for a water content of 0.3 % wt. The amphibole stability fields derived from both compositions are consistent with previous results obtained for Earth-like composition: (i) the water-saturated fluid-absent conditions expand the stability field towards higher pressures and temperature compared... more
