Haxtun

Description

Note that there are two separate specimens featured in this video:
0:00 Haxtun #1
1:36 Haxtun #2

The Meteorological Society has that Haxtun is “a weathered stone of 15.5 kg was found in a wheat field. Research material, thin section, classification as H/L4 and analysis, olivine, pyroxene, kamacite. The bulk analysis gives an L classification: total Fe 20.9 ± 0.5% (avg. of 5 samples): 20.5% total Fe, low siderophiles, Ni 0.92%, Co 436 ppm, Ir 0.46 ppm, Se 12.8 ppm, low alkalies, Na 0.37%, K 500 ppm” and “this is 1 of 90 approved meteorites from Colorado… and 1 of 1,929 approved meteorites from US.”

Mindat additionally includes that it has “well-defined chondrules, mostly barred olivine with smaller amounts of pyroxene-rich types, are intergrown within a dark, fine-grained matrix. Very nearly equilibrated olivine and orthopyroxene are accompanied by Fe-Ni metal and troilite. The Fe-Ni metal and troilite are frequently founds as irregular aggregates near chondrule rims. Minor amounts of plagioclase and chromite are also reported. Total Fe (~21 wt%) as well as silicate composition indicate an H/L chondrite. Mosaicism in olivine is indicative of significant pre-terrestrial shock (level S3). Iron oxides at the rims of metal grains and as narrow veins are indicative of significant terrestrial weathering (level W4).”

The Colorado Meteorite Society estimates a total of around 45kg has been found to date, and while meteorites in general have so much that so many would find interesting and worthwhile of collecting, these will probably find their home with a Colorado rock lover before a meteorite collector gets the opportunity!

Be sure to keep your eyes out for rocks like these and you might also just be able to find a new meteorite and make a new discovery!
