Geology rocks and minerals

Chromite, an oxide mineral, is the major ore of chromium. It is often used for the bricks and linings of blast furnaces as it can withstand very high temperatures. Chromite is one of the first minerals to crystallise in deep ultra mafic magmas, and becomes concentrated as it sinks to the bottom of the magma chamber.

Chromite Physical Optical Properties, Uses, Occurrence

Almost pure chromite is found in similar layers in sedimentary rocks. The layers are preserved when the sedimentary rocks metamorphose to form serpentinite. Referred to as chromitites, these rocks are the most important ores of chromium. The weathering of chromite ore bodies can also lead to its concentration in placer deposits.

Peridotite: Igneous Rock Pictures, Definition & More

Peridotite bodies are also found by prospecting for some of the rare minerals that they contain. When a peridotite weathers, the olivine breaks down, quickly leaving the more resistant minerals behind. Geologists have loed peridotite bodies by prospecting for chromite, garnet, and other resistant indior minerals.
