<u>The best estimated pressure is 110 GPa</u>. Pressures in the lower mantle begin at 24 GPa and reach up to 136 GPa at the border between core and mantle. For the most part it is composed of a single mineral called perovskite. Recent experiments show that this mineral with iron content is very unstable in the lower mantle.
The two types are Alcoholic fermentation and lactic acid fermentation.
