A stone was found in the desert, D.Weber, priv. comm., 1998. Description, mineralogy and bulk chemistry, an unusually metal-rich (60-70% FeNi) carbonaceous chondrite breccia, related to CH chondrites, such as Acfer 182, ALH 85085, and also related to Bencubbin, Weatherford and the CR chondrites, J.Zipfel et al., LPSC 29, 1998, abs. #1417.
