Ordinary chondrite, (L6, br)
Find,1894; 17 kg
A triangular mass had been found near a dry creek bed and other stones were found later. The fusion crust was eroded away and the dark interior surface is often browned by stains, but small grains of Fe-Ni metal were still apparent. The interior is coarsely granulated with rare and indistinct chondritic structures, but clearly brecciated with fractured crystals and interstitial glass. Careful examination reveals grains of olivine [Fa25], orthopyroxene [Fs22]('Bronzite'), albitic plagioclase, and very small troilite grains. Olivine grains reach diameters of 0.2-0.4 mm. Accessory chromite is present, invariably associated with the metal and/or troilite. Some highly shocked aggregates even have ringwoodite- and majorite-bearing fragmental aggregates. Rubin and others have argued that Ness County (1894) belongs to a strewn field that also includes the Wellmanville and Franklinville stones.
The Field Museum of Natural History (Chicago) obtained and has retained a large fraction of the Ness County mass. However, moderate-sized masses have also been obtained by the American Museum of Natural History (New York), the United States National Museum (Washington), Arizona State University, and the University of California in Los Angeles.
