Geochemistry: Pathways and Processes
We conclude, therefore, that if the partial pressure of C02 in a weathering
environment <2.6 X 1074 atm, no siderite is formed. The stable phase, instead,
would be magnetite. The upper stability limit of siderite produced during
weathering is set ...

of 10 6 the siderite stability field would disappear altogether. In this case the
choice of a low equilibrium [Fe2+] is not reasonable since siderite in nature is
found in environments high in [Fe2+] (Postma, 1981, 1982). The boundaries at [
Fe2+] ...
