100% of the exterior is covered with brown/black fusion crust. The interior is rusty brown and moderately hard. |
The section consists of 70-80% round, elongate and irregular metal particles typically 100-200 microns in diameter but reaching 1 mm. These particles are separated by terrestrial hydrated iron oxides. Chondrules occupy 20-30% of the rock and occur in similar shapes and sizes as metal. They are fine-grained and dominated by barred, microporphyritic and cryptocrystalline texture. Silicates are iron-poor (Fa3-4, Fs1). The meteorite is similar in many respects to QUE 94411 and may be paired, although it was recovered more than 5 km from QUE 94411. |
Reclassified as CBb Chondrite in AMN 31,1.
