Gao Guenie Meteorite, Oriented, Rollover Lipping, Flowlines, 17g


On March 5th, 1960, a bright fireball exploded over the largely rural area of Burkina Faso. Local villagers witnessed the fall and many kilograms of stones were recovered. Later analysis proved the stones were H5 chondrites. Some specimens show an alternate impact melt breccia lithology.

This specimen is an oriented shield with a distinct rollover lip. It appears to be a stone that broke apart in mid-flight, with secondary crust on the broken portion. The rest of the stone is covered in primary fusion crust. There are some faint flowlines visible along the outer edges on the leading side. The trailing side of the stone is bumpy and frothy. It weighs approx. 17 grams.
