Writeup from MB 103:

Križevci        46°02’20"N, 16°35’23"E

Croatia

Fell: 4 Feb 2011

Classification: Ordinary chondrite (H6)

History: This meteorite was tracked as a fireball by the Croatian meteor network on the night of 4 February 2011 and found following a search of the fall area on 20 February 2011. The orbital characteristics have been determined and precise mapping of the morphology of the meteorite used to determine its disintegration characteristics in the atmosphere. The fireball was observed to fragment several times in the photographs which led to predictions of the strewn field just to the east of the town of Križevci and possibly several large pieces to be found. A search was mounted and a single stone was found.

Physical characteristics: Single stone, black fusion crust.

Petrography: (I. Lyon, UMan). Abundant Fe/Ni metal grains typically up to 500 μm in size. Absence of chondrules, possibly a few relicts. Silicates typically large 50-200 μm.

Geochemistry: (I. Franchi, OU) Oxygen isotopes, δ17O = 2.755, δ18O = 3.985, and Δ17O = 0.683 permil: I. Lyon, UMan; EPMA metal grains Ni 5.5, Co 0.5, Fe 94; Ni 49, Co 0, Fe 51 (all wt%)

Classification: K. Korlevic, I. Lyon, UMan; Ordinary chondrite (H6)

Specimens: 291 g, single stone. Held by K. Korlovic, VO.
