Element association of Oxygen in the Mineral World
This table compares the known valid mineral species listed listed with Oxygen 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 Oxygen and the element listed for that row.

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

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 Oxygen
This list of minerals containing Oxygen 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 Oxygen mineral species. It is more useful when comparing rare species rather than common species.
