Hi all,

I am new in this forum, I am pleased that this forum was created! I am working in serpentinites and serpentinized peridotites of spinel stability field. I tried to make pseudosections (database tcdb55c2d) with the system FMASHO with excess water and 40% of Fe2O3 but with no luck, I think that maybe the problem is not considering the solution models of antigorite.

I was wondering if somebody has a solution model for an antigoritite for example the one that have perplex (antigorite with tschermak substitution; Padrón-Navarta et al., 2013, Lithos )

Thank you!
