Writeup from MB 104:

Cedar Lake        32°50.67’N, 102°28.28’W

Texas, United States

Find: 1998

Classification: Ordinary chondrite (H5-6)

History: Finder sent the stone to B. Barnett (submitter) for identification

Physical characteristics: One mass of 509 g was located during cultivation for farming. The piece has a partially intact, brown, weathered fusion crust.

Petrography: This meteorite contains barred olivene(BO) and radiating pyroxene (RP) chondrules, many of which contain igneous rims. Chondrule size measurements showed a large range from 250-600 μm; however, most chondrules are hard to delineate in this sample due to recrystallization. Plagioclase is around 50 μm in some areas, however, it is not completely uniform and there are smaller grains in the section as well.

Geochemistry: Average compositions are as follows Olivine (N = 25) Fa19.5±.2, Orthopyroxene (N = 28) Fs17.0±0.2En81.7±0.2Wo1.30±0.22, Clinopyroxene (N = 7) Fs7.1±1.6En48.8±0.4Wo44.1±1.4, and Plagioclase (N = 11) Ab82.8±1.3An11.5±0.2Or5.7±1.3.

Classification: Ordinary chondrite (H5-6); the sample is heavily weathered (W3). This is apparent both in hand sample and thin section; most of the native metal has been oxidized. Shock stage, S1.

Specimens: Only one mass is known. It is in the possession of Brian Barnett, 4091 Mather, Kyle, Texas.
