these assemblages are compatible with the following phases or species
determined by component saturation or buffering constraints:

--------------------------------------------------------------------------------

The Y(CO2)  -T(K)     loci of (pseudo-) univariant fields follow:

the fields are subject to the constraint(s):

                         P(bar)  = 1000.00    

These fields are consistent with saturation or buffering constraints
on the component(s):CaO  

NOTE: For each field the values of the dependent  extensities are output
for the first equilibrium condition, in general these properties vary with
the independent potentials.


Reaction equations are written such that the high T(K)    
assemblage is on the right of the = sign
