Rocks approaching this model composition are herein called 'pyrolites' A study is made of the mineralogy and geological environment of naturally occurring pyrolites. Such rocks occur as xenoliths in kimberlites and basalts and also in some intrusive peridotites. They are observed to crystallize in one of four distinct mineral assemblages: (1) olivine+amphibole, (2) olivine+plagioclase+pyroxenes, (3) olivine+aluminous pyroxenes+spinel, or (4) olivine+pyrope garnet+pyroxenes. Evidence regarding the geological occurrence and experimental stability of these assemblages is reviewed, and the relative P-T stability fields of the different assemblages are inferred. The ability of the pyrolite model composition to crystallize in a number of very distinct mineral assemblages controlled by pressure and temperature would lead to large-scale mineralogical zoning in the upper mantle. Such zoning will have an important effect on many properties of this region, particularly including the seismic velocities. References Boyd, F. R., J. L.
