Manganese as a chromophore in minerals and gems
Mn2+Usually gives a pink to red colour to minerals, such as rhodonite and rhodochrosite. In a tetrahedral site such as in willemite it can give a yellow-green colour.
Mn3+causes red and green colours in octahedral sites. In red muscovite from brazil, red beryl from Utah, piemontite from Whitewater, California. It can also give a green colour to andalusite and in a tremolite from New York it produces a violet colour. It also causes the purple colour in charoite.
Mn4+The green colour in freshly-mined spodumene (eg from the Oceanview Mine) is due to the 4+ ion, but it is rapidly reduced in sunlight to 3+ causing a colour change to pink.

Geochemistry of Manganese
Goldschmidt classification:Siderophile
Mn2+ was one of the ions least depleted from the mantle in the formation of the crust.
Mn3+ enters early-forming phases in igneous rocks.
Mn4+ enters early-forming phases in igneous rocks.
Mn2+ enters early-forming phases in igneous rocks.
Mn3+ is commonly concentrated in residual soils and sediments.
Mn4+ is commonly concentrated in residual soils and sediments.
Mn3+ is concentrated in deep-sea ferromanganese nodules relative to seawater.
Mn4+ is concentrated in deep-sea ferromanganese nodules relative to seawater.
Mn2+ solute can be a limiting nutrient in the growth of bacteria.

Element association of Manganese in the Mineral World
This table compares the known valid mineral species listed listed with Manganese and the other elements listed based on the official IMA formula. Note that unlike other sections on this page this includes non-essential elements.

The first data column contains the total number of minerals listed with Manganese and the element listed for that row.

The second data column lists this number as a percentage of all minerals listed with Manganese.

The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row.

Most widespread minerals containing Manganese
This list of minerals containing Manganese is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Manganese mineral species. It is more useful when comparing rare species rather than common species.
