Davy(a), 1940 Texas Farm Find, L4 Chondrite, Micromount

Davy(a), 1940 Texas Farm Find, L4 Chondrite, Micromount


Davy(a) is a football-sized (3.77kg) meteorite that was first found in 1940 and is not to be confused with another meteorite found in the same area, Davy(b). Davy(a) was found on rural farmland in De Witt County Texas. It has been classified as an L4 chondrite that is quite weathered with a long terrestrial age and it has experienced moderate shock (S2). Davy(a) is a classic American meteorite find and is very representative of many other meteorites found on Texas ranchlands by farmers or other local residents. The main mass of this meteorite sits in the Monnig Collection at TCU.
