Geochemistry of Dysprosium
Goldschmidt classification:Lithophile
Dy3+ was one of the ions least depleted from the mantle in the formation of the crust.
Dy3+ is enriched in Ca-Al-rich inclusions in meteorites relative to the composition of the solar system.
Dy3+ is concentrated in residual soils and sediments (less certainty.)

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

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

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