Mafic and ultramafic igneous rocks host practically all primary PGM ore of the world.
It is primarily made up of ultramafic silicate rocks.
In mafic and ultramafic igneous rocks and thermally metamorphosed impure dolomitic limestones(Anthony et al., 2001- 2005).
In potassium-rich mafic and ultramafic lavas(Anthony et al., 2001- 2005).
Layer 3 is formed by slow cooling of magma beneath the surface andconsists of coarse grained gabbros and cumulate ultramafic rocks.
A secondary component in altered ultramafic rocks(Anthony et al., 2001- 2005).
Ultramafic rock- igneous and meta-igneous rock with a very low silica content(less than 45%), composed of usually greater than 90% mafic minerals….
Also from andesitic volcanic and altered ultramafic rocks(Anthony et al., 2001- 2005).
Typically a product of retrograde metamorphism, replacing olivine, orthopyroxene, orother minerals in ultramafic rocks(Anthony et al., 2001- 2005).
Enstatite- specimens[gallery view]In peridotites, ultramafic inclusions in alkalic olivine basalts and kimberlite;
Produced by regional or contact metamorphism of magnesium carbonate,mafic, or ultramafic rocks(Anthony et al., 2001- 2005).
The usual thickness of continental crust is about 2.7 g/cm3,less dense than the ultramafic substance that makes up the layer, which has a thickness of around 3.3 g/cm3.
Characteristic of some granite pegmatites associated with mica schists orreaction zones in ultramafic rocks(Anthony et al., 2001- 2005).
A gangue in hydrothermal veins;in carbonatites and ultramafic rocks(Anthony et al., 2001- 2005).

The relative rarity of crocoite is connected with the specific conditions required for its formation:an oxidation zone of lead ore bed and presence of ultramafic rocks serving as the source of chromium(in chromite).
The average density of continental crust is about 2.7 g/cm3,which is very less dense than the ultramafic material that holds up the main mantle, having a density of around 3.3 g /cm3.
