Writeup from MB 106:

Hocheppan        46°29.1’N, 11°12.75’E

Trentino-Alto Adige, Italy

Find: 2016 Oct 16

Classification: Ordinary chondrite (H5)

History: Dieter Janek discovered the meteorite during a mountain hike on a dolomitic hillsite at Gantkofel, 2.5 km WSW of Hocheppan castle on October 16, 2016.

Physical characteristics: One nearly complete stone of 1136 g, covered with dark-brown fusion crust and minor, small broken faces. Cut face shows dark-gray matrix with lighter inclusions, chondrules and abundant fresh metal.

Petrography: (R. Bartoschewitz, Bart) Microscopic examination of a thin section shows dark matrix with very fine-grained groundmass and various types of chondrules of 0.1-1 mm (average 0.4 mm) in diameter. Lighter inclusions with coarser groundmass and various chondrule types of 0.3 - 1.2 mm (average 0.6 mm) are embedded in the dark matrix. Metal is homogenously distributed in both lithologies.

Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa17.6±0.3 (n=35); pyroxene Fs15.6±0.4Wo1.5±0.4 (n=8). Kamacite Ni=6.3, Co=0.6 wt.-%). Magnetic susceptibility (R. Bartoschewitz, Bart) log χ (× 10-9 m3/kg) = 5.34.

Classification: Ordinary chondrite (H5)

Specimens: 20.0 g on deposit at Kiel, main mass (1126.6 g) Dieter Janek, Eppan
