Writeup from MB 103:
Faina 15°26’46"S, 50°21’38"W
Classification: Iron meteorite (IAB complex)
History: Found in a backyard when Mr. G. Rodrigues dug a hole for septic tank of his house. He suspected that the mass was a meteorite after watching a TV program about meteorites. Purchased by Andre Moutinho on 31 Aug 2013.
Physical characteristics: A mass weighing 440 g and measuring about 7 × 4 × 5 cm.
Petrography: (M.E. Zucolotto, MNRJ) Exhibits a microscopic Widmanstätten structure typical of plessitic octahedrites, with kamacite spindles of 80±20 μm. Schreibersite bodies are very common, mostly with swathing kamacite. Faina resembles Ballinoo, Cratheús (1950) and several other plessitic octahedrites from group IIC.
Geochemistry: (J.T. Wasson, UCLA) INAA: 8.67% Ni; 23.4 ppm Ga; 82 ppm Ge; 3.91 ppm Ir; 1.42 ppm Au. Composition of major phases (I.P. Ludka, IGEO-UFRJ) WDS/EPMA: kamacite (Ni=5.56±0.4; Co=0.61; N=20), taenite (Ni=28.8±1.4; Co=0.61; N=16), phosphides (Ni=27.7±1.2; P=16.68±0.7, N=12), all in wt%.
