Ordinary chondrite, veined (L6)
Found, 1954; 13 kg

An unusual L chondrite with shock-induced melt veins. Unusually high pressure phases include ahrensite, akimotoite, lingunite, stishovite, and ringwoodite.

Shock stage S4 to S6 due to transient shockwaves with instances of crystallization occurring at ~18 MPa.
