Writeup from MB 105:

Castelvecchio        43.98483°N, 10.72317°E

Toscana, Italy

Find: 2015

Classification: Iron meteorite (IIAB)

History: On 3 Aug 2015, a lumberjack appointed by meteorite collector Mario Goiorani to explore the area with a metal detector and a GPS, found several bomb slivers and a single small, rounded, metallic sample completely covered by rust and buried in the ground at a depth of about 10 cm.

Physical characteristics: The main mass, 37 g, displays an ablated outer surface. It was cut on one side to get the type specimen. No Widmanstaetten pattern was visible on the etched surface.

Petrography: (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi). A 1 cm × 1 cm chip of the sample was analyzed by SEM. No exsolution lamellae were detected in BSE in the exposed area. A SEM X-ray linescan performed across the entire section provided a homogeneous kamacitic composition with no appreciable variations.

Geochemistry: SEM-EDX spot analyses, all in wt.% (V. Moggi Cecchi, G. Pratesi, S. Caporali, UniFi): kamacite Fe95.1±0.5Ni4.5±0.5 (N=5); Bulk composition (C. Herd and G. Chen, UAb): Ni=59.4, Co=4.7 (both mg/g); Cu=141, Ga=55.5, Ge=166, As=4.1, W=1.3, Ir=0.07, Pt=3.2, Pd=2.3, Ru=3.0, Os=5.2, Rh=1.6, Ag=0.6, Sb=0.3 (all μg/g). Obtained by solution ICP-MS using North Chile (Filomena) as an internal standard.

Classification: Iron meteorite (IIAB). Hexahedrite.

Specimens: The remaining of the main mass, weighing 26 g, is owned by Mario Goiorani. An 11 g sample and a polished section is on deposit at MSN-Fi.
