How Is Peridotite Formed?
Layered peridotites are igneous sediments and form by mechanical accumulation of dense olivine crystals. Some peridotite forms by precipitation and collection of cumulate olivine and pyroxene from mantle-derived magmas, such as those of basalt composition.
What is the main composition of peridotite?
Peridotite
| Type | Igneous Rock |
|---|---|
| Chemical Composition | Ultramafic |
| Color | Dark Gray to Black |
| Mineral Composition | Pyroxene (Bronzite), Olivine |
| Tectonic Environment | Upper mantle; sometimes obducted at continent-continent collision zones |
