Bernd, Mark and Dean, Thank you for your responses on NWA R-chondrites. My comparison is that my two slices of 978 looks a lot fresher than my two 753 slices and one individual, which are more oxidized (orange colored) than the 978 I have. The chondrules appear to be rounder and smaller too in the 978. The 782 and 800 ones are also relatively fresh looking, but to me they look different from 753 and 978. The 978 and Dean's latest material look alike by my comparisons, and yes Bernd they have light colored chondrules in a greyish black matrix that is like looking into the milky way. Very nice material. The new piece from Dean had a fair amount of white caliche on the exterior, but the interior is fresh looking.
The price of these R meteorites ($7 to 20/g), along with Allende($4 to 5/g), Bilanga ($12 to 18/g), Gao ($1 +/-), Zag ($0.50 to $2/g), SA ($0.30 to $1.00/g) offer some of the best deals out there right now for great falls and finds. What a time to build a collection.
