metamorphic
Greenschist, blueschist, zeolite, granulite and eclogite high grade metamorphic rocks.
Extreme metamorphism of oceanic crustal basalt.
The rocks found in the mantle are usually olivine, pyroxenes, spinal structure minerals, and garnet. Some others are peridotite, dunite, and eclogite.
It's eclogite facies.
In the earth's crust
Two reasons: first, peridotite is native to the mantle where as eclogite is formed from the metamorphism of oceanic crust; secondly, eclogite has a much higher density than peridotite and so it sinks to the lower mantle.
The mantle, or interior of the Earth is made up of mostly of rocks that have high amounts of silicon and aluminum. There is also an abundance of nickel and iron in the mantle.

the source is the magma
Rocks of the mantle are peridotite, dunite, and eclogite. In deeper regions, the olivine may be replaced by more stable minerals.
quartzite, slate, gneiss, marlbe, migmitite, amphibolite, serpenrinite, eclogite. that's all i have from my school papers. quartzite, slate, gneiss, marlbe, migmitite, amphibolite, serpenrinite, eclogite. that's all i have from my school papers.
The rock cycle is how one type of rock can be changed into another type of rock.
