Mineral deposit Magmatic cumulates Britannica
Mineral deposit Mineral deposit Magmatic cumulates: Magmatic segregation is a general term referring to any process by which one or more minerals become locally concentrated (segregated) during the cooling and crystallization of a magma. Rocks formed as a result of magmatic segregation are called magmatic cumulates. While a magma may start as a homogeneous liquid, magmatic segregation

Magmatic Segregation Mining Fundamentals
When the mineral content present in magma crystallizes, it sinks down and settles at the bottom of the magma chamber as it is denser than the magma. Some of the commonly formed mineral deposits formed due to magmatic segregation are iron, granite, aluminum, diamond, chromite, and platinum.
