Non-silicates: Sulphates, Carbonates, Phosphates, Halides
Phillips and Brown (1987) described the occurrence of siderite, ankerite and

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 ...

United States Geological Survey Professional Paper
In general, quartz and pyrite exhibit a characteristic affinity, and siderite and
galena are similarly related. Thus low-grade ore is usually (not always) quartzose
and pyritic, while rich ore con sists chiefly of galena and siderite. In the Jersey ore
