I need the detailed answer​

Answer 1

Answer:

Diamond is an evidence for carbon existing in the deep earth. Some diamonds are considered to have originated at various depth range from the mantle transition zone to the lower mantle. These diamonds are expected to carry significant information about the deep earth.

Explanation:

We determined the phase relations in the MgCO3-SiO2 system up to 152 GPa and 3,100k using a double sided laser-heated diamond anvil cell combined with in situ synchrotron X-ray diffraction. Mg CO3 transform from magnesite to the high pressure polymorph of Mg CO3, phase ll, above 80 GPa. A reaction between Mg CO3 phase ll and SiO2.
