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 ...

As long as part of the iron remains in the ferrous condition, reaction with
limestone will precipitate supergene siderite. When exposed to weathering such
siderite eventually alters to one form or other of the ferric oxide minerals, and
when ...

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+] ...
