Pyrolite
Pyrolite is a term used to characterize a model composition of the Earth's mantle. This model is based on that a pyrolite source can produce the Mid-Ocean Ridge Basalt by partial melting. It was first proposed by Ted Ringwood (1962) as being 1 part basalt and 4 parts harzburgite, but later was revised … See more The major elements composition of pyrolite is about 44.71 weight percent (wt%) SiO2, 3.98 wt% Al2O3, 8.18 wt% FeO, 3.17 wt% CaO, 38.73 wt% MgO, 0.13 wt% Na2O. 1) A pyrolitic See more Whether pyrolite could represent the ambient mantle remains debated.

WebMar 23, 2024 · The density of pyrolite is smaller than those of harzburgite and MORB before the pSp transition in pyrolite occurs, in which the density differences (pyrolite minus harzburgite or MORB) are −0.17 g/cm 3 just before the pSp transition. The density crossover occurs between pyrolite and the other rocks due to the pSp transition in pyrolite.
