Writeup from MB 110:
Sentinel Plain (d) 32°53’27.78"N, 112°59’30.78"W Arizona, United States Find: 13 Apr 2019 Classification: Ordinary chondrite (L6) History: A 119 g meteorite was found by Mr. Robert Szczuczko on 13 April 2019, while he was searching for meteorites in southwestern Arizona. Physical characteristics: Single 119 g blocky fusion-crusted stone with shallow regmaglypts. The interior is gray with a few scattered rust colored areas. Few chondrules are visible and metal is heterogeneously distributed. Petrography: (L. Garvie, ASU, R. Szczuczko) A 5 × 4 cm slice shows a heterogenous distribution of metal. Low metal areas show no recognizable chondrules and sparse metal with grains to 3 mm. Examination of a thin section shows the chondrule- and metal-poor regions to be heavily recrystallized; these areas are typically light gray. Areas with finer grained and dispersed metals show a few recognizable chondrules. Feldspar typically 20 to 60 µm. Relatively abundant, anhedral chromite, to 200 µm. Geochemistry: Fa25.4±0.5, n=17; Fs21.5±0.5Wo1.7±0.3, n=8 Classification: L6, S2, W1 Specimens: 21 g at ASU | ||||||||||||||||||||||||||||||||||||
