[ Meteoritical Bulletin Database ]


Classification: Chondrite H4 S2 / W0-1
Place/Time: 2004  in Texas, USA
Mass: 16.8 kg

History: Found in 1999 by Mr. Darrel Ellis while plowing a cotton field located 0.5 mile south on Highway 82 from the Wellman, Texas, water tower then east 0.25 mile. Mr. Ellis stored the unusually dense stone in his garage until it was purchased on October 11, 2004 by McCartney Taylor. Portions of the mass were subsequently sold to various collectors including Eric Twelker and Marcin Cimala.
Petrography: (A. Irving, UWS, and J. Boesenberg, BrownU) Well-defined relatively small, equilibrated chondrules containing devitrified glass are set in a relatively coarse-grained matrix containing very fresh kamacite (with only rare Fe oxide staining), taenite, troilite, chromite and chlorapatite, but no plagioclase.
Classification: Ordinary chondrite (H4). Pairing with other meteorites found in the Wellman area has not been assessed in details, but five out of the six other classified specimens found in the Wellman area since 1940 are also H chondrites (the class for the other OC specimen is not known).
Specimens: 20.5 g plus one polished thin section at UWB; remainder with Mr. M. Taylor and others including Twelker and Mr. M. Cimala.
