Chondrite (L4), shock stage S3, weathering grade W0-1.
Fell October 25, 1984.
Recovered weight: 42 kg.

After the appearance of a fireball, a small shower fell with 4 stones being recovered, the largest 25 kg. The meteorite contains fairly well-defined chondrules closely packed together within a dark matrix, but some incipient integration of chondrules into the matrix is observed. Olivine (Fa24.4) is well equilibrated, but pyroxene (Fs14-23) is still incompletely equilibrated. Most of the low-Ca pyroxene is orthopyroxene, but ~20% is monoclinic (clinopyroxene). Fe-Ni metal and troilite are frequently found near chondrule rims. Undulose extinction and fracturing in olivine account for the S3 shock level classification.

A cosmic ray exposure age of 15.7 Ma is reported.
