Meteorite di Castiglione del Lago, Castiglione del Lago, Provincia di Perugia, Umbria, Italia


Iron meteorite, IAB-MG, coarse octahedrite. Composition is consistent with IAB Complex, Main Group (MG).

A single mass, weighing 667 g, was recovered in 1970 near Castiglione del Lago by a peasant while plowing his field. The peasant preserved the sample for many years in his home considering it just a curiosity until he read in 2007 an interview of the well-known Italian meteorite collector Matteo Chinellato, who invited people to send him potential meteorites for analysis. Chinellato received the main mass, cut a slice and sent it to Museo di Scienze Planetarie (MSP), Prato, and Museo di Storia Naturale dell'Università degli Studi di Firenze (MSN-Fi), Florence, for analysis. An end-cut, weighing 27.2 g, is preserved at MSP; a polished thin section at MSN-Fi.

Although silicate inclusions are visible on the cut and etched specimen, the 1 × 1 cm polished section examined does not contain silicates. Metal is formed by coarse-grained (~4 mm width) equigranular kamacite grains with 120° grain boundaries, inside which Neumann lines are visible. Taenite is rare. Scattered schreibersite laths, up to 100 microns in width and to 1 mm in length, can be observed within some kamacite grains and at grain boundaries, frequently surrounded by iron oxides. Bulk composition include Ni=66.4 mg/g, Co=4.4 mg/g; Cu=151 μ/g, Ga=98.2 μ/g, Ge=414 μ/g, W=1.4 μ/g, Ir=4.2 μ/g, Pt=8.1 μ/g, Pd=3.5 μ/g, Ru=7.0 μ/g, Re=0.3 μ/g, Os=1.4 μ/g, Ag=1.6 μ/g, Sb=0.5 μ/g.
