Iron, IIIAB (Om) - shock-hardened, weathered
Found 1922, 20 kg

Two similar and badly oxidized masses (11.3 kg, 9.1 kg) were plowed up about 5 km southwest of Glasgow. The pieces were so weathered that Widmanstätten figures were visible without etching. The smaller was sent to the U.S. National Museum. The meteorite's dominant lithology is its shock-hardened kamacite with troilite nodules. Fe-Ni metal [~7.6% Ni] also includes taenite ribbons and plessite. Troilite, often with included daubréelite, is present. Schreibersite is also found, particularly at grain boundaries. Lawrencite, a corrosive Cl-bearing weathering product first discovered in meteorites, is all too evident.

As of 2000, 4.047 kg still remained with the U.S. National Museum in Washington, DC.

ⓘ Lawrencite

Formula: (Fe²⁺,Ni)Cl₂

Description: A corrosive product of terrestrial weathering discovered in iron meteorites. For several decades this Cl-bearing mineral was incorrectly believed to be a preterrestrial component of some meteorites.
