Of Seymchan pallasite metal and fragments of the iron "facies" Glorieta Mountain and Brenham also contain large regions Olivine grain size and metal:olivine ratios with metal veins up to tens ofĬm in thickness. Photographs of this new (2004) material show great heterogeneity in The meteoritic literature is slowly catching up with thisįascinating find. Most intriguing, the finds in the 2000s have revealed that perhapsĨ0% of the material is iron, but the remaining 20% is pallasite. Was later reclassified as an "ungrouped iron" (Wasson and Wang, 1986). With kamacite bandwidth 2.0 mm, and early analyses returning 9.47 and 9.15% nickel Identified as a coarse octahedrite, a IIE iron meteorite It is clear that the current recovered mass is far greater, North via the Kolyma River to enter the East Siberian Sea The two pieces, 20 metres apart, were reportedlyĬhannel, on the west side of the main branch of the Hekandue River, that flows The first find in 1967 was followed by a second mass, reported total
Surrounding the pallasite "lens" ( olivine and kamacite), with coarseīronze-coloured axe-head crystals ("rhabdites") of the iron-nickel Metal, largely a nickel-iron alloy ( kamacite), Is only now receiving wide attention, due to much Seymchan is a meteorite find from the Magadan "Rock of the Month #127, posted for January 2012". Immediate provenance: Eric Wichman / Michael Miller. As with a smooth rock outcrop,Ī sawn slice shows just two dimensions of a 3-D reality, Segregating one from the other, as coeval and Or if the two "facies" (metal-silicate and metal) Pallasite is intruding iron, or vice versa, This is not unknown in Seymchan material and To be a lens or vein of pallasite "facies" material What appears (caveat: at the scale of the palm of your hand!) The slice is remarkable for displaying the contact between
Of the Seymchan meteorite, 143.92 grams, circa 11.2圆.0x0.45 cm in size. Mingled within one or more fragmented metre-scale masses found in Siberia Seymchan Meteorite displaying "facies" of both pallasite and iron meteorite
