[meteorite-list] Acapulcoites are the third most common meteoritetype.

Hello Martin,

As for NWA 725, here are the details as Stan shared them with me:

Recent O-isotopic analysis of a probable paired stone (number pending) 
by the Open University resolves the material clearly within the 
winonaite field:
"In particular, the D17O value of -0.431 is in reasonable agreement with 
the mean value of -0.48 for the winonaite-IAB iron-IIICD iron group 
determined by Clayton and Mayeda (1996)."
In addition, when plotted on a diagram comparing the D17O-isotopic value 
vs. Fa mol% in olivine (Rumble, III et al., 2005), NWA 725 (Fa 6.1; 
D17O-isotopic value taken from the paired stone [Turecki, 2005; pers. 
comm.]) and the winonaites NWA 1463 (Fa 7.4; D17O = -0.45‰), NWA 
1457 (Fa 5; D17O = -0.40 ±0.03‰), and NWA 1058 (Fa 6.5; D17O = 
-0.53‰) all plot very close together within the winonaite field. 
The inference can thus be made that NWA 725 is actually a winonaite, 
likely paired with the primitive winonaites NWA 1463 and 1058.
