It was formed from deep sea or mantle rocks.

Many died huddled together at Mantle Rock waiting to cross.

Mantle rock was always buried beneath miles of crust.

It has only been discovered in a small variety of places from upper mantle rock to meteorites.

You never saw exposed mantle rock on Earth.

Because the pressure is not as great at this level, the mantle rock will melt, forming magma.

This is one of the few known examples where sea floor mantle rocks are exposed above sea level.

At the lowest level are mantle rocks such as serpentinite and harzburgite.

Like bees collecting nectar, they stopped under the mushroom-shaped mantle rocks.

Wouldn't think so, the planet's so small that its core can't possibly have enough heat energy to move whole continents of mantle rock.

This occurs because rifting of the lithosphere allows hot mantle rock to move towards the surface.

Yellowstone lies over a hotspot where light, hot, molten mantle rock rises toward the surface.

Three thousand kilometers of pure mantle rock?

Most likely they are derived from hydrated mantle rocks, probably harzburgites or lherzolites.

That is where the mantle rock is forced by sidewise pressure against the passing cosmic string.

At Mount Olympus, the highest point of the massif, mantle rock is visible.

Studies of glacial rebound give us information about the flow law of mantle rocks and also past ice sheet history.

That has stretched the crust, making it thinner and bringing hot mantle rock closer to the surface, which has warmed things up.

The increased water content lowers the melting point of the mantle rock in this wedge, causing it to melt into magma.

Their spatial arrangement thus underlines major thrust planes bringing these mantle rocks into higher crustal levels.

The mantle rock is peridotite.

At the same time erosion resulted in stripping of the outer mantle rocks and further modeling of terrain.

Debate continues whether these mantle rocks were a fluid and/or metal source, or simply reflect a favourable pathway.

As the two plates separate, the mantle rock from the asthenosphere layer below flows up into the void between the plates.

He also performed studies on the distribution of metals present in petroleum, comparing them with the mantle rocks, chondrites, crust, and seawater.
