Extended Data Fig. 2: Mantle pseudosections for Kilbourne Hole lherzolite xenoliths KH-11, KH-29, and KLB-1.
From: Active crustal differentiation beneath the Rio Grande Rift

The assemblage for KBH lherzolites (clinopyroxene-orthopyroxene-olivine-spinel) is outlined in green. Average temperatures Fe-Mg and Na exchange between coexisting clinopyroxene and orthopyroxenes are calculated using the calibration of Brey & Köhler (1990)31.
