I've been looking at my two small slices over and over again tonight at different magnifications (8x, 16x, 32x). Of course, like all the others, I just can't resist guessing what it might be - so my guess is that it not what a "typical" brecciated aubrite like Pena Blanca or Cumberland Falls looks like. It's much more "microcrystalline" and reminds me of my NWA 4413 slice (an L6 chondrite) with regard to the tint of the blue "variety" and also because of the highly "microcrystalline" texture. If it is chondritic, I would assume it is an EL6, if it is aubritic I would expect something like AUB-ANOM. This guessing game is fun but it will be even more fun when we finally get to know what this oddball really is and how far we (me and all the others) were off the mark. Moreover, let's remember that enstatite chondrites and aubrites are "relatives", relatively speaking ... that is ;-) Bernd Received on Fri 30 Nov 2007 05:37:48 PM PST |
