Hello all >From another information from The Meteorite Collection at the Department of Earth Sciences, University of Modena, Italy, from the W.R.Van Schmus $ J.A.Wood, 1967 - Geoch. Cosm. Acta 31, 747, the Albareto meteorite is classificated a LL4 chondrite, but in the all catologue of the others meteorite collections in Italy - La Sapienza, Rome is L4 - Albareto is put on L4 type. The unique is another modern classification of the meteorite, I know the responsable of the Modena University, and have many little pieces for analysis. Regards
