Writeup from MB 104:

Watson 014 30°33’3.80"S, 131°43’3.30"E

South Australia, Australia

Purchased: 2013 Apr 06

Classification: Ordinary chondrite (H3)

History: Three jigsaw-fitting fragments found by A Tomkins

Physical characteristics: The fusion crust suggests that these three jig-saw fitting fragments represent 70% of the sample.

Petrography: (A. Tait, Monash) Chondrule edges are well defined in an opaque microcrystalline matrix. Chondrule sizes ranges from 0.5 -2.0 mm. Chondrule types include: POP, RP, GOP, BO, PP, PBO. Some olivine grains show weak undulose extinction, but no evidence of higher shock indicators. Minor oxidation has occurred (<5%), as thin rims around some metal grains.

Geochemistry: (A. Tait, Monash) FEG-SEM analyses show that olivine and pyroxene are uniform in their composition: olivine Fa_18.1-18.8, mean Fa_18.5±0.2, n=12; Low-Ca pyroxene Fs_15.6-16.3, mean Fs_16.0±0.3, n=13.

Classification: Ordinary chondrite (H3, S2, W1)

Specimens: All specimens and one thin section held by A. Tomkins.
