Pizhanka        57°20.42’N, 48°30.15’E

Kirovskaya oblast’, Russia

Find: May 2016

Classification: Iron meteorite (IAB-MG)

History: Single piece of iron (46.78 kg) was found by Mr. O.N. Rykov while he was plowing fields near Akhmanovo and Pizhanka in May 2016.

Physical characteristics: The meteorite has an elongated, irregular, heart-like shape; it is covered by a shell of iron oxides. Total weigh is 46.78 kg.

Petrography: The polished and etched section (150 cm2) reveals coarse kamacite plates, ranging from 6 to 12 mm (8.18±2.52 mm, n=11), with sets of parallel Neumann lines and intergrowths of rhabdite needles. Patches of recrystallized kamacite are sparsely distributed on the surface, and particularly concentrated around a large troilite-graphite inclusions. Three large (15 × 25, 20 × 10, 12 × 15 mm) and some small knobby troilite nodules with swathing 1-3 mm schreibersite are present. Schreibersite occurs as scattered, cuneiform, skeletal crystals 0.3-2 mm in size, with 20-100 µm wide, discontinuous grain-boundary veinlets.

Geochemistry: Mineral compositions and geochemistry: (N. N. Kononkova, Vernad, EMP) kamacite: Ni =7.40±0.07 (N=4), Co = 0.53±0.05 (N=4), P = 0.23±0.02(N=4); taenite: Ni = 29.9±3.15 (N=8) (all in wt%); schreibersite: Ni =37.3±0.68 (N=4), P = 14.5±0.29(N=4); rabdite: Ni =47.0±1.61 (N=4), P = 13.8±0.65(N=4); (J.T. Wasson, UCLA): INAA data, Ni = 67.4, Co = 4.65 (both mg/g), Au = 1.593, Ga = 83.2, Ge = 422, Re = 0.254, Pt = 5.66, Ir = 2.74, Cr = 22, W = 1.02, As = 12.7, Cu = 119 (all µg/g).

Classification: Iron, IAB-MG, Ogg

Specimens: Total 5616.88 g and thick section are on deposit at Vernad.
