A Brenham pallasite slice mounted in titanium alloy — 11 g, 24 × 42 mm at 4.6 mm thick. The elongated proportion suits this material: olivine grains are scattered irregularly through the nickel-iron, and a longer window catches more of them than a compact one would.
Specification
Meteorite: Brenham, pallasite (olive meteorite)
Weight: 11 g
Dimensions: 24 × 42 × 4.6 mm
Setting: titanium alloy
Reference: LK042
Olivine in metal
A pallasite is a stony-iron meteorite: crystals of olivine suspended in a nickel-iron matrix. Held against light the olivine reads translucent green while the metal around it stays opaque. No two slices carry the same distribution — the crystals sit where they happened to settle.
Care
The metal phase contains iron and will corrode in open air, so each piece is sealed with an epoxy coating before it ships. Avoid abrasives and prolonged soaking.
