DEFINITION OF DIAMOND ANVIL PRESS AND MULTI-ANVIL PRESS

The diamond anvil press and multi-anvil press are scientific equipment

that re-create the high pressures found deep within and

at the center of the Earth and in other celestial bodies. They

provide scientists with indirect ways to study the conditions

and mineral phases present deep in the Earth. The diamond

anvil press is the smaller of the two and is only able to put

small amounts of material under about 100 GPa of pressure,

or roughly about the pressure found at the center of the

Earth. The multi-anvil press is a larger press and can accommodate

more material but can produce far less pressure

(about 11 GPa) compared to the diamond anvil press. The

diamond anvil press can experimentally produce greater

amounts of pressure, but the multi-anvil press is more widely

used because it can accommodate greater amounts of material

that can be studied after the experiment. Many of the diamond

and multi-anvil presses can also pass electric current

through the samples that reproduce higher temperatures

found inside the Earth.

Mineral physicists mainly use olivine, a silicate mineral,

to represent the upper mantle and also iron and nickel combinations

to represent the core in the high pressure experiments.

The diamond anvil press and the multi-anvil press

have allowed scientists to learn about how the core and the

mantle separated. They have also been used to study the

phases and stabilities of minerals at high pressure, earthquakes

that occur deep inside the Earth, and the properties of

other materials at high pressure and temperatures.
