The association of carbonate alteration of banded iron

iron ores occur as tabular bodies of soft friable hematite with smaller lenses of hard (compact) massive hematite. The hard hematite lenses typically occur at the contact with the underlying metavolcanic rocks of the Parauapebas Formation surrounded by an aureole of hydrothermal carbonate alteration in both overlying and underlying rocks.

Iron sulfide (FeS) OilfieldWiki

Iron sulfide (FeS) In the oil/gas industry, iron sulfides are often present in a sour system due to reaction between corrosion products and hydrogen sulfide. They can deposit in the production tubing or on the pipe wall and accumulate in separators. Dry powdered iron sulfide is pyrophoric (ignites spontaneously when exposed air), which poses a significant HSSE risk.
