ultramafic rock

The mountain is made from ultramafic rock of unknown age.

Chesterite is usually found in thin sheets within ultramafic rocks.

It is also found as shears in ultramafic rocks.

This is due to the ultramafic rock - peridotite - which makes up the Tablelands.

The important known nickel deposits are in the ultramafic rocks of the lower cycle, around 2700 Ma old.

These deposits are found in mafic and ultramafic rocks.

The Earth's mantle is composed of ultramafic rocks.

Subvolcanic ultramafic rocks and dykes persist longer, but are also rare.

The most dense sima has less silica and forms ultramafic rocks.

Platinum and palladium are precious metals generally found in ultramafic rocks.

It was affected by metamorphism and contains outcrops of ultramafic rocks.

Within the region, ultramafic rocks, the original source of the cobalt and nickel, are confined to the project area.

Common types of caprock are sandstone and ultramafic rock types.

Mafic and ultramafic rocks take up significant CO2 through their natural alteration processes.

It occurs in an ultramafic rock deposit.

Importantly, large volumes of ultramafic rocks are not found in association with Proterozoic anorthosites.

Ureilites bear some similarities to certain ultramafic rocks from the Earth's lower crust or upper mantle.

Ore deposits of this type are restricted to the weathering mantle developed above ultramafic rocks.

The ultramafic rock of the upper mantle can be melted by the addition of volatiles from below.

Ultramafic rocks also contain elevated amounts of chromium and nickel which may be toxic to plants.

Weathered ultramafic rocks may form lateritic nickel ore deposits.

One example concerns crystallization of melts that crystallize to mafic and ultramafic rocks.

They often form a relatively thin layer over a base of ultramafic rock and are thus known as ultramafic soils.

There are five oval shaped masses of mafic to ultramafic rocks making up the ophiolite.

It also occurs in andesite volcanic rocks and altered ultramafic rocks.
