Bernic Lake        50°26.307’N, 95°31.762’W

Manitoba, Canada

Found: October 2002

Classification: Iron meteorite (IAB-MG)

History: In October 2002, the discovery of two irregularly shaped meteorite fragments weighing 5.5 and 4.3 kg was reported to the Prairie Meteorite Search (run by the Universities of Calgary, Western Ontario and Regina) by Derek Erstelle from Winnipeg, Manitoba. The discovery site is east of Lac du Bonnet, 3.6 km from the junction with Highway 315 along the Tanco Mine Road. Bernic Lake, the site of the Tanco Mine, is the nearest geographical feature and is the source of the name. The two fragments were found in a sandy area within 5 m of each other.

Physical characteristics: The two specimens are heavily weathered to reddish-brown oxides that penetrate along fractures into the interior

Petrography: (S. Kissin, LHU) Etched sections show average bandwidth of 4.3 ± 1.3 mm (n=19). Kamacite lamellae are stubby and irregular, and contain abundant Neumann lines. Taenite is limited to minute lamellae and blebs. Schreibersite is present as sparse Brezina lamellae and rhabdites.

Geochemistry: (S. Kissin, LHU): Ni = 65, Co = 4.3 (both mg/g); Cu = 130, Ga = 83, Ge = 353, As = 11.3, Ir = 3.32, Pt = 6.5, and Au = 1.4 (all in μg/g) obtained by INAA (Actlabs)

Classification: Iron meteorite, IAB-MG, coarsest octahedrite (S. Kissin, LHU)

Specimens: Two main masses, 5086 g and 4076 g, were acquired by the ROM. A 444 g slice was removed from the larger mass and transferred to UAb.
