| Geochemistry of Zinc | |
|---|---|
| Goldschmidt classification: | Chalcophile |
| Zn2+ was one of the ions least depleted from the mantle in the formation of the crust. | |
| Zn2+ is concentrated in residual soils and sediments (less certainty.) | |
| Zn2+ solute can be a limiting nutrient in the growth of bacteria. | |
| Zn2+ solute is a micronutrient on land. | |
| Zn2+ is essential to nutrition of at least some vertebrates ('essential minerals'). | |

| Element association of Zinc in the Mineral World | |||
|---|---|---|---|
| This table compares the known valid mineral species listed listed with Zinc 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 Zinc and the element listed for that row. The second data column lists this number as a percentage of all minerals listed with Zinc. The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row. Click on a heading to sort. |

| Most widespread minerals containing Zinc |
|---|
| This list of minerals containing Zinc 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 Zinc mineral species. It is more useful when comparing rare species rather than common species. |
