The core is located at the center of the earth. It has both liquid and solid parts and is extremely hot, from 2200-5000 degrees Celsius at one time. The core makes up about 1/3 of Earths mass, but only about 15% of its volume.

Geologic Occurrence. Unakite is a metamorphic rock that forms when granite (an igneous rock) is altered by hydrothermal activity.During metamorphism, plagioclase in the granite is replaced by epidote to produce a rock composed primarily of green epidote, pink orthoclase, and clear to bluish-gray quartz. 2 Unakite can also contain minor amounts of magnetite, chromite,
Unakite Gemstone is the name used for a coarse-grained granitic rock that, after metamorphism, contains abundant pink orthoclase and pistachio-green epidote.
