Thank you, Al ! It is always a pleasure to hear from you :-)

Right - and here an excerpt from the
conclusions reached by the authors:
WANG M-S., MOKOS J.A. and LIPSCHUTZ M.E. (1998) Martian meteorites:
Volatile trace elements and cluster analysis (Meteoritics 33-4, 1998,
p. 671, excerpt):
These similarities suggest that the six Martian meteorite subtypes
derive from as many sources within the planet, with each being closed to
volatile element transfer. Since even vapor transfer did not occur, the
components of each Martian meteorite subtype can be considered as
reflecting source region compositions and, therefore, suitable for more
exacting investigations like those of Ghosal et al. (1997).
GHOSAL S. et al. (1997) Shergottite evidence for a reduced,
iron-depleted Martian mantle (Meteoritics 32-4, 1997, A046).
GHOSAL S. et al. (1998) Evidence for a reduced, Fe-depleted
Martian mantle from shergottites (Contr.Min.Petr. 130, p. 316).
Best wishes,
