Meteorite di Trenzano, Trenzano, Brescia, Lombardia, Italia
Unequilibrated ordinary chondrite, veined (H3/4)
Fall, 12 November 1856; 11.8 kg, 2 stones
The first meteorite fall near Brescia. For most of the 20th Century, Trenzano was classified as a more or less normal ordinary chondrite — listed as an 'olivine-bronzite' chondrite in the Prior (1923) catalogue, an H6 in the Grady (2000) catalogue. Indeed while prominent chondrules are present, the matrix olivine (Fa19) and pyroxene (Fs17) are equilibrated within most of the meteorite. Other components such as Fe-Ni metal and troilite are just those expected in an ordinary H-chondrite. Closer inspection, however, has revealed variable plagioclase-feldspar compositions, glass, and other features inconsistent with such a simple classification. A more precise classification indicates a monomict breccia that contains an admixture of unequilibrated L-chondritic material (type H3) with the more equilibrated L-chondritic material (~type H4). In our current classification scheme, then, Trenzano becomes one of only 44 witnessed unequilibrated ordinary chondrite falls.
While 35 meteorites have been classified precisely as 'H3/4' chondrites, Gütersloh and Trenzano are the only witnessed H3/4 chondrite falls currently listed at the Meteoritical Bulletin Database (Oct 2015).
