Monte Costone        45°46.57’N, 9°43.30’E

Lombardia, Italy

Find: 2020 Jun 16

Classification: Ordinary chondrite (H5)

History: The meteorite was found by Federico Pogliani, the owner of the main mass. He usually walked, together with his dog, on Monte Costone’s paths because he is a collector of roe-deer antlers and minerals. Pogliani observed the presence of this dark object in a zone where usually the colors of rocks are light.

Physical characteristics: The 224 g meteorite appeared completely covered by a dark-gray fusion crust and had magnetic properties. The main mass was cut in 3 pieces of 11.3, 20.8 and 191.9 g in addition to a thin section.

Petrography: The meteorite shows the typical features of ordinary chondrites: abundant chondrules include porphyritic olivine, radial pyroxene, granular, and barred olivine chondrules, including porphyritic olivine, radial pyroxene, granular and barred olivine types, with size range 0.1 - 1.5 mm in diameter. In many chondrules, the mesostasis shows partial to extensive devitrification, up to the crystallization of feldspar. Most of the metal phases show amoeboid shape. Plagioclase crystals up to 50 μm in size

Geochemistry: The composition of phases was determined with a JEOL JXA 8530-F (with WDS-EDS detectors) at NHMV by Dr. L. Pittarello. Plagioclase An11-43.

Classification: Ordinary chondrite (H5)

Specimens: Type specimen at UPad, main mass with Federico Pogliani
