The database is updated with a complete review concerning the elements: Cr, Co, Sr and Fe.
The update also concerns clay minerals (both hydrated and anhydrous), zeolites and minerals related to cement materials.
Among the new or recently reviewed minerals in the database, we have included vivianite, fluorite, imogolite. Data concerning silica complexes have been reconsidered with respect to high strength ionic solutions.
Several bugs have been fixed concerning namely the PHREEQC header and inconsistencies in element masses. Supernumerary aqueous complexes have been removed.
Mineralogical comments relating to genesis conditions have been reviewed; the task is still going on.
