Source Lodders (1998) Shergotty and QUE94201 are basaltic shergottites, ALH 77005 is a lherzolitic shergottite, ALH 84001 is an orthopyroxenite, Nakhla is a nakhlite, and Chassigny is a chassignite. Analytical uncertainties are Is deviations for multiple analyses. 

Mantle contamination by addition of variable amounts of upper crustal material (e.g. metapelites) to peridotite, possibly represented by both harzburgite and lherzolite.

While all spinel-lherzolite facies suites show remarkably similar compositional trends as a function of depletion, some garnet peridotite xenoliths in kimberlites and lamproites from ancient cratonic lithospheric keels show signih-cantly different trends (e.g., see Boyd, 1989 Chapters 2.05 and 2.08). Most of these xenoliths are extremely depleted extrapolation of the trends back to the PM MgO of 36.7% gives similar concentrations of Si02, EeO AI2O3, and CaO to the spinel Iherzolites (O Neill and Palme, 1998) the difference in their chemistry is due to a different style of melt extraction, and not a difference in original mantle composition.

Finally, the Ronda peridotites are generally characterized by negative anomalies of zirconium on PM-normalized diagrams, the amplitude of which increases from lherzolites (which have only subtle anomalies) to dunites. Zr/Sm is mostly in the range (O.S-l)XPM in the lherzolites.
