# NASA data for LAP 031370 Weathering: B Fracturing: A Fa: 24 mol % Fs: 21 mol %
The exterior is dull and rusty with oxidation haloes. This iron is shaped like a fish.
We examined this small meteorite in polished section from a central slice. The section consists of ~90% kamacite with abundant Neumann bands that vary in spacing from a few to a hundred microns. No heat altered zone or α₂ structure was observed. Included within the metal are polyminerallic silicate inclusions that reach a few mm in diameter with included metal, troilite, chromite and pentlandite and a kidney-shaped troilite inclusion 1.2 mm in length. The silicates are broadly chondritic and relict barred chondrules are present. Silicates are homogeneous with olivine of Fa₂₄ and orthopyroxene of Fs₂₁. The meteorite is an ungrouped iron.
