Is goethite a metamorphic?
Goethite is an iron oxyhydroxide. The formation of goethite is marked by the oxidation state change of Fe2+ (ferrous) to Fe3+ (ferric) iron, which allows for goethite to exist at the earth’s surface. Hematite is one of the most abundant minerals and is found in sedimentary, metamorphic, and igneous rocks.

limonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O). It was originally considered one of a series of such oxides; later it was thought to be the amorphous equivalent of goethite and lepidocrocite, but X-ray studies have shown that most so-called limonite is actually goethite.

|Hematite||5.5.- 6.5||Red and reddish brown|
|Augite (pyroxene)||6||dark green to black|

Microcline is a common rock-forming mineral of granitic rocks and pegmatites, and is often secondary after othoclase.
