Ordinary chondrite, black (LL7)
Fell, 12 June 1840; 710 g

After detonations a small meteorite was observed to fall. A fusion crust is observed in current photographs and some shock-induced darkening is evident upon inspection. Composition of olivine (Fa30.3) and orthopyroxene (Fs23.5) indicate membership in the LL (very low bulk iron) ordinary chondrite group. The predominate olivine and orthopyroxene are accompanied by accessory Fe-Ni metal, troilite, feldspar, and clinopyroxene. Small amounts of apatite, chromite, and merrillite are also present.

Uden is one of 98 LL and L/LL ordinary chondrite falls [as of November 2015]. However, Uden is the only LL chondrite currently classified as an LL7. Petrologic type 7 meteorites have been heated to the point of local melting, but have not experienced significant chemical-mineralogical migration and differentiation.

The main mass has been kept at the Noordbrabantsch Museum in the Netherlands.
