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

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

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 Fluorine
This list of minerals containing Fluorine is built from the 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 Fluorine mineral species. It is more useful when comparing rare species rather than common species.
