Writeup from AMN 5(1):
Sample No.: RKPA80258 Location: Reckling Peak Field No.: 1071 Weight (gms): 4.3 Meteorite Type: Mesosiderite
Physical Description: Roberta Score Fusion crust covers one surface of this meteorite. Visible on it are two large clasts, probably pyroxene, measuring 1.0 x 0.5 cm and 0.5 x 0.4 cm in dimension. both show cleavage faces. The specimen is highly weathered, although metal was detected in chipping. Sample is paired with RKPA80229, RKPA80246, and RKPA80263. Dimensions: 1.5 x 1.5 x 1 cm
Petrographic Description: Brian Mason The section shows angular clasts of orthopyroxene up to 2 mm across in a nickel-iron matrix, closely resembling RKPA79015, RKPA80229, and RKPA80246. A thick rind of red-brown limonite rims part of the section. Microprobe analyses show some variability in pyroxene composition: Wo2.3-2.9, En77-80, Fs17-21, in contrast to RKPA79015, RKPA80229, and RKPA80246, in which the pyroxene has essentially uniform composition of Wo2En74Fs24. Rare grains of calcium-rich plagioclase of somewhat variable composition (An86-An94) were noted. The unique nature of these specimens and their otherwise close similarity indicates that they are probably pieces of a single meteorite, a metal-rich mesosiderite. | ||||||||||||||||||||
