Writeup from MB 105:
Ooldea 010 30°34’10.2"S, 131°46’20.4"E South Australia, Australia Find: 9 Apr 2013 Classification: Ordinary chondrite (L5) History: Single fragment with distinct chondrules found by A. Tomkins. Physical characteristics: No fusion crust, numerous well-formed chondrules visible, 60% of the 5 cm slightly elongate sample covered by lichen. Petrography: (J. Savage, A. Tait, Monash) Chondrule boundaries are difficult to differentiate from the matrix. Large porphyritic chondrules, ~1 mm, can be distinguished from the matrix. The matrix is no longer opaque and has an olivine-pyroxene-plagioclase composition. Matrix still maintains a large porosity. Chondrite mineralogy includes olivine, pyroxene, Fe-Ni Metal, troilite and plagioclase. Chondrule types present are BO, POP, RP, C, PP and PO. Both sharp and undulose extinction are common in olivine, pyroxene and plagioclase grains. Olivine grains shows mosaicism and conjugate pair fractures, that offset into the matrix in some grains. Fe-Ni metals exists a coarse grains (<0.6 mm) and as fine-grain inclusions in chondrules. Fe-Ni metals show minor oxidation (<10%) and is restricted to the coarse grain metals. Troilite shows <5% weathering. Geochemistry: (J. Savage, Monash) Microprobe analyses show that olivine and pyroxene compositions are uniform: olivine Fa22.0-23.9, mean=Fa22.9±1.7, n=6; Low-Ca pyroxene Fs23.5, n=1. Classification: Ordinary Chondrite (L5, S2, W1). Specimens: The main mass and a thin section are held at Monash, under the curation of A. Tomkins. | ||||||||||||||||||||||||||||||||||
