Writeup from MB 101:
Dhofar 1672 (Dho 1672) 18°43’56.8"N, 54°22’45.7"E Zufar, Oman Found: January 2011 Classification: Ordinary chondrite (L4) Petrography: (P. Strickland, UAb) Approximately 80 vol% chondrules, 15 vol% matrix, and <5 vol% metals/opaques. Chondrules have an average diameter of 1 mm and display porphyritic and some radial pyroxene textures. Most chondrules are readily delineated with the exception of a few well-defined radial pyroxenes. Most of the chondrule glass is absent due to the presence of secondary feldspars <45 μm, however there are still minor amounts of devitrified glass present. Matrix is recrystallized, transparent, and relatively coarse. Olivine and pyroxene grains contain irregular fractures, planar fractures, undulatory extinction, and some melt pockets consisting of multiple FeNi droplets <10 μm. Strongly mosaic olivine is also present. Plagioclase has mostly undergone transition to maskelynite (S5). Dominant rusty staining and abundant oxide veinlets indicate moderate weathering (W3). Geochemistry: (C. Herd and P. Strickland, UAb) Olivine Fa24.9±1.1 (n=37); Low-Ca pyroxene Fs22.2±1.9Wo2.2±1.6 (n=46); Augite Fs13.9±4.9Wo33.9±12.0 (n=11). Classification: Ordinary chondrite (L4). Classified based on average and standard deviation of Fa and Fs content in olivine and low-Ca pyroxene, respectively. Specimens: 3.3 g type specimen, including polished thin section, are on deposit at UAb. Remainder at SQU. | ||||||||||||||||||||||||||||||||||
