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,

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
