1.5" Etched Saint-Aubin Iron Meteorite Slice (22.2 g) - France
This is a 1.5" wide (22.2 grams) piece of the Saint-Aubin iron meteorite Aube, France. It has been nicely cut/etched into a thin slice to display the complex Widmanstätten pattern.
The Saint-Aubin Meteorite
The Saint-Aubin meteorite is a 472-kilogram iron (IIIAB) meteorite that landed in Champagne, France roughly 55,000 years ago. Farmers found five pieces in 1968 as they plowed fields.
Saint-Aubin contains the minerals sarcopsite and graphtonite, two related iron-nickel phosphate minerals, as well as long crystals of schreibersite, an iron-nickel phosphide mineral. It was originally classified as "ungrouped", but more recent work has shown it is a high-nickel, high-gold, low-iridium member of the (IIIAB) group. It often contains well-defined Widmanstätten patterns, and sometimes contains shock features such as Neumann lines, a shock-hatched kamacite structure.
