June 9, 1952: Abee Meteorite Falls in Canada

On This Day, June 9, 1952: Abee Meteorite Falls in Canada, Abee formed near the sun as a chondrite with petrologic vary times and it would contain little or no water. Unlike most other chondrites, the minerals in enstatite chondrites contain almost no iron oxide.
The largest known recorded E-type chondrite fall happened in the town of Abee, in Alberta in 1952. The 107 kilograms (236 lb) stone fell in a farmer's wheat field, creating an impact pit 0.7 m in diameter and 1.5 m deep.[3] Based on estimates of its velocity and inclination, it is thought to have arrived on a relatively low-speed, low-inclination orbit
The largest known E-type chondrite in the asteroid belt may be 21 Lutetia
The chondrite Abee has been found to contain excess amounts
of inert dust. From their amounts and isotopic compositions, it is concluded
that these are of primordial origin.
Enstatite chondrites contain a variety of unusual minerals that can only form in extremely reducing conditions, including oldhamite (CaS), niningerite (MgS), perryite (Fe-Ni silicide), and alkali sulfides (e.g., djerfisherite and caswellsilverite). it has been suggested that the ex Planet but today Asteroid 16 Psyche, may be the common parent for this type of meteorite.
