The WGME comprises geoscientists who work with experimental and thermodynamic modeling of mineral equilibria and apply models to determine the physico-chemical and geodynamic conditions of formation of both magmatic and metamorphic rocks.

The WGME was created in 1978. The group's activity includes two major items: (1) participation to international meetings and (2) publication of special volumes.
The group is open to everybody. The WG includes about 10 permanent members.

Following council recommendations reported during the Vancouver Business Meeting in 2008, the WGME officers have to move. There was a too long position as IMA-WGME officers for some of the officers.

The 2008 annual report was received on the 27^th of October from the Executive Secretary, Oleg Safonov.
