Angrite, volcanic.

A 16.55 kg stone, mostly covered with dark gray fusion crust, was found in 1979 in a corn field after a farmer hit it with a plow. Two decades after its recovery, D'Orbigny was classified as an angrite. In fact, D'Orbigny is by far the most massive Angrite. Angrites are characterized by their low alkali contents, high Ca/Al ratios, and a somewhat variable but still distinctive mineral assemblage (e.g., various Ca, Al, &/or Ti-rich phases).

Angrites are also very ancient rocks. Recent crystallization ages ≥4.562 billion years have been reported for D'Orbigny (Amelin, 2007; Spivak-Birndorf et al., 2009) making it one of the oldest known differentiated rocks in the solar system.


Note on the mineral list:
http://www.lpi.usra.edu/meteor/metbull.php?code=7714 also mentions a silicophosphate (probably a "silicoapatite").
