Writeup from AMN 5(1):
Sample No.: RKPA80259 Location: Reckling Peak Field No.: 1292 Weight (gms): 20.2 Meteorite Type: E5 Chondrite
Physical Description: Roberta Score Thin iridescent fusion crust covers most of this stone. The matrix is dark colored and weathered. A small amount of white evaporite deposit is present in the interior of the sample. Dimensions: 2.5 x 1.5 x 1.5 cm
Petrographic Description: Brian Mason Chondrules are area and barely discernable, the meteorite consisting largely of fine-grained enstatite (mean grain size approximately 0.05 mm), with some nickel-iron and troilite. Weathering is very extensive, with much red-brown limonite throughout the section. The silicate material is blackened. by the presence of finely dispersed troilite, probably the result of an episode of severe shock. Microprobe analyses showed that the enstatite is almost pure MgSiO3; with minor amounts of Al2O3 (0.1-0.3%), FeO (0.1-0.5%), and CaO (0.5-0.8%). The meteorite is classified as an E5 chondrite. | ||||||||||||||||||||
