Knardna 002 31°00’07.0"S, 130°54’33.2"E South Australia, Australia Find: 16 May 2012 Classification: Ordinary chondrite (H4) History: Found by A Langendam on a claypan Physical characteristics: Dark red-black rounded sample with 65% fusion crust. Petrography: (A. Tomkins, Monash) The matrix and mesostases are fine-grained and barely recrystallized. Chondrules edges are distinct, and vary significantly in size and composition (varieties include RP, BO, PO, PP, POP, GOP, C). Very small plagioclase grains (< 10 μm) can be distuinguished in reflected light. Olivine has weak undulose extinction; there is no shock melting. Metal grains are completed destroyed by rusting, and some troilite remains. Geochemistry: (A. Tomkins, Monash) Microprobe analyses: olivine Fa19.2-20.4, mean Fa19.7, std=0.26, n=8; Low-Ca pyroxene Fs16.4-18.9, mean Fs17.38, std=0.40, n=12. Classification: Ordinary Chondrite (H4, S2, W4) | ||||||||||||||||||||||||||||||||||||||
