Girgenti meteorite, Agrigento (Girgenti), Provincia di Agrigento (Provincia di Girgenti), Sicilia, Italia
Several meteoritic stones, classified as L6 chondrite, which fell on 10 February 1853 near Agrigento (at that time, Agrigento was called Girgenti). The total recovred mass is about 18 kg.
A mineralogical and chemical study performed on the largest mass (8750 g) of the Girgenti meteorite, from the collection of the Smithsonian Institution, Washington, D.C., showed that its mineralogical composition is: forsterite (Fa24–25), enstatite (Fs21 –22), plagioclase (An12), "maskelynite", whitlockite, nickel-iron alloys (abundant taenite and scarce kamacite), troilite, chromite, and ilmenite. Girgenti is a severly metamorphosed stone, whose total iron content (23.5%) is somewhat higher than the average for hypersthene chondrites (Levi-Donati & Jarosevich, 1972).
