Name: Lonewolf Nunataks 94100 This is an OFFICIAL meteorite name. Abbreviation: LON 94100 Observed fall: No Year found: 1994 Country: Antarctica [Collected by US Antarctic Search for Meteorites program (ANSMET)] Mass: 1947 g
Macroscopic Description: Kathleen McBride
This meteorite is shaped like a volcanic bomb and has a rusty-colored,
exfoliating, flaky exterior. It is dull on one side and shiny
on the opposite side. Thick evaporitic material is present on
two exterior surfaces. The flaky crust has numerous surface cracks
that do not penetrate the interior and run mostly in the longitudinal
direction. The weathered crust extends a few millimeters into
the interior. The interior is very fresh compared to the exterior
and proved to be very coherent and extremely hard. The interior
is fine-grained and varies in color from steel-gray to black with
interstitial white to clear crystals.
Thin Section (,6) Description: Brian Mason
Only vague traces of chondritic structure are visible in the thin
section, which shows the meteorite to consist largely of granular
to prismatic enstatite (grain size 0.1-0.2 mm), about 20% nickel-iron,
minor amounts of sulfides, and a little plagioclase. The enstatite
is almost pure MgSiO3 (Fe 0.1-0.6%, Ca 0.7-0.9%). The metal contains
0.9% Si. One grain of plagioclase, An17, was analyzed. The meteorite
is an E6 chondrite.
