Writeup from MB 100:

Windimurra        28°5’49.1"S, 118°27’20.2"E

Western Australia, Australia

Found: 2004

Classification: Ordinary chondrite (H4/5)

History: Several large, fractured and broken, crusted masses and many smaller fragments totaling more than 30 kg were found scattered on the surface over a large area near Windimurra Station. The first find was about 3 km N of Kantie Murdana Hill.

Physical characteristics: (A. Bevan, WAM). Some fragmental material retains fresh, black fusion crust. Chondrules are clearly visible on broken and cut surfaces. Fresh metal (with only very minor oxide staining) and discontinuous, elongated, thick (up to 2 mm) metal veins are also evident on some sections.

Petrography: (A. W. R. Bevan, WAM, and A. Tomkins, Monash). Chondrules with devitrified mesostases are well pronounced. Chondrule types including porphyritic olivine, porphyritic pyroxene, barred olivine, radiating pyroxene and cryptocrystalline, occur in a generally microcrystalline matrix. In some pyroxene chondrules, grains of polysynthetically twinned clinopyroxene occur. Metal grains are heterogeneously distributed and large metal grains and metal and troilite veins locally invade the fabric of the meteorite. A large elongated clast of dark, fine-grained H-group material was observed in one section. Accessory minerals include chromite.

Geochemistry: (A. W. R. Bevan and P. Downes, WAM). Olivine Fa19.7±0.3; low-Ca pyroxene Fs17.8±0.4Wo0.36-1.3; chromite (in the H-group clast), Fe# 85.0, Cr# 85.1; kamacite, Ni=6.8, Co=0.50 (both wt.%).

Classification: Ordinary chondrite (H4/5); S2; W1

Specimens: Main mass and four thin sections at WAM.
