Macroscopic Description: Roberta Score Shallow regmaglypts are present on exterior of this fusion crusted stone. Most of the interior that was exposed by chipping is weathered but may not be representative of the entire stone. The less weathered material is medium gray in color and contains chondrules.
Thin Section (,3) Description: Glenn MacPherson Light to moderate limonitic staining indicates mild weathering. Chondrules up to 2.5 mm diameter are sharply defined. Brown glass is turbid and birefringent. Monoclinic pyroxene is abundant and has an observed composition range of Fs20 to Fs32. Olivine was found in the composition range Fa23 to Fa28. Metal (mostly one phase) and troilite are subequal in amount. This meteorite is probably an L4 chondrite. | ||||||||||||||||||||
