Hello all!

The old Monahans iron has been classified by Buchwald (pp. 832-834) as
an anomalous plessitic octahedrite related to Dorofeevka (Kazakh SSR)
with which it has many structural and chemical features in common.

Monahans (1938):

One mass of 27.9kg was found 7 miles south and 1 mile east of Monahans,
