Common oxide minerals include: hematite and limonite. Hematite Hematite is identified by its non-metallic or metallic luster and its red to red-brown streak. Hematite Hematite is identified by its non-metallic or metallic luster and its red to red-brown streak.
Limonite. Limonite is scientifically not considered a true mineral as it lacks a definitive chemical formula and crystal structure. However, all mineral reference guides list it together with other minerals. Limonite is a matrix base of many other minerals, and the term gossan is used as a reference to Limonite when it is used as a a matrix for

Limonite is an iron ore consisting of a mixture of hydrated iron oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mined for the production of iron since at least

This research revealed that the material called "limonite" does not meet the definition of a mineral. Instead, limonite is a mineraloid composed mainly of hydrous iron oxides that are often found in intimate associations with iron minerals. Today the word "limonite" is used as a field and classroom term for these materials because they cannot be identified in hand specimens and their identity is unknown without

02.09.2019· Luster, the way a mineral reflects light, is the first thing to observe in a mineral. Luster can be bright or dull, but the most basic division among the various types of luster is this: Does it look like a metal or not?The metallic-looking minerals are a relatively small and distinctive group, worth mastering before you approach the nonmetallic minerals.
The streak test is valuable because many minerals occur in a variety of apparent colors but all specimens of that mineral share a similar streak color. For example: specimens of hematite can be black, red, brown, or silver in color and occur in a wide variety of habits ; however, all specimens of hematite produce a streak with a reddish color.
