Resumen:
Partition coefficients (KDs) in mantle xenoliths from Ea. Poklepovic, Santa Cruz province, Argentina, were calculated. The comparison of the obtained KDamphibole/cpx1 and KDcpx2/melt with published data shows that (a) amphibole crystallised in equilibrium with matrix clinopyroxene and (b) as suggested by petrographic evidence, secondary clinopyroxene and glass from melt pockets are not in equilibrium.
