620 kg.   Iron, ungrouped

TKW 626 kg. Fall not observed. Found 1828, Provence-Alpes-Cote d'Azur, France.



From Buchwald:
A mass of about 625 kg was reported by Thury (I829) and Brard (I829), who realized that the large chunk of iron situated in front of the church in Caille and used as a bench was a meteorite. The mass was purchased for the Paris Museum, and a few kilograms have since been distributed.

The [main] mass is roughly in the shape of an irregular pyramid with the approximate average dimensions 65 x 50 x 50 cm. It is exhibited in the Paris Museum in Jardin des Plantes and shows various interesting surface features. Most of the surface is corroded with a terrestrial oxide crust of up to several millimeters thickness. Locally, the corrosion attack has weakened the adhesion between the Widmanstiitten lamellae, so that octahedral fragments can be detached.

Characteristic are the 25-30 holes, which are found on many parts of the surface and appear to be parallel. They are 15-50 mm in diameter and 20-50 mm deep and of a more or less flat, cylindrical-conical shape. It appears that they once contained parallel troilite cylinders which partly burned out in the atmosphere, partly corroded away or were scraped out by curious people.

Thanks Hanno...seeing specimens from Museums is a nice way to share some impressive meteorites that we might not see otherwise.
