Hello All, Gao, Chergach, Pultusk, and other ordinary chondrites often have their impact melt portions ignored when being characterized. Chelyabinsk would be the most recent obvious example of this -- "LL5 S4 W0" Except, when you read the petrographic description:
"...A significant portion (1/3) of the stones consist of a dark, fine-grained impact melt containing mineral and chondrule fragments. Feldspar is well developed and practically isotropic. No high-pressure phases were found in the impact melt. There are black-colored thin shock veins in both light and dark lithologies." http://www.lpi.usra.edu/meteor/metbull.php?code=57165 We collectors see impact melt and think it's cool, but it's secondary information for the classification, I think.
