Unequilibrated ordinary chondrite, microbrecciated (LL3.4)
Fall, 10 August 1968; 13.1 g

A widely observed fireball crossed over the Aegean Sea before reaching Italy where detonations were followed by the formation of a cloud of dust. According to calculations, the meteorite exploded about 20 km above the ground over the village of Piancaldoli (Firenzuola municipality). 3 small meteorite fragments (7.55 g, 5.1 g, 0.41 g), partially covered with a fusion crust, were recovered from a rooftop of a small house (lat. 44°14'39.5" N, long. 11°30'08.4" E) in the municipal territory of Castel del Rio (Bologna Province, Emilia Romagna), 6 km from Piancaldoli. Chondrules (0.5-2.0 mm) — olivine- and pyroxene-rich — dominate a microbrecciated and unequilibrated population of silicates, phosphates, and opaques embedded within a black groundmass. While the primary components are largely unshocked, numerous small petrographic features (glass, exsolution lamellae…) indicate that a number of small grains and fragments had experienced previous shocks before aggregation into the current assemblage. Both olivine and pyroxenes are highly unequilibrated. Individual grains of nearly pure enstatite and forsterite are found within a larger population of more typical LL chondrite olivines and pyroxenes. Pyroxenes, in particular, exhibit a variety of mineralogical species reflecting different compositional environments and cooling regimes. Sulfides — troilite, pyrrhotite, and pentlandite — exhibit additional compositional and textural features indicative of variations in formational oxygen fugacities. While the actual amount of material recovered from the Piancaldoli fall was quite modest, the thorough investigations of Carapezza, Nuccio, and Valenza revealed remarkable petrographic and mineralogical variations. Such a rich mineralogical inventory is normally reported from other, larger unequilibrated chondrites only after studies over many years or even decades.

Piancaldoli is one of only 44 witnessed unequilibrated chondrites falls. Of these falls, only 3 of them are classified as exactly 'LL3.4' — Chainpur, Manych, and Piancaldoli.
