| Geological Setting：Large ore bodies of hematite are usually of sedimentary origin; also found in high-grade ore bodies in metamorphic rocks due to contact metasomatism, and occasionally as a sublimate on igneous extrusive rocks ("lavas") as a result ov volcanic activity. It is also found coloring soils red all over the planet... | |
