Csátalja        46.006°N, 18.991°E

Bacs-Kiskun, Hungary

Find: 2012 Aug

Classification: Ordinary chondrite (H4)

History: Excavated during plowing of a cultivated field on a farm near Csátalja, Hungary, in August 2012. The farm owner brought the stone to Dr. Tibor Hegedűs at the BajaAO, who sent small samples to scientists at the University of Bratislava, University of Eötvös Lóránd and University of Pécs, where initial optical and X-ray diffraction testing confirmed it to be a chondrite. The find location is 4.8 km SE of the village of Csátalja.

Physical characteristics: A single brown, roughly equidimensional stone originally weighing ~16 kg. The average value of the magnetic susceptibility is 5136×10-5 SI, with 7448×10-5 SI within the metal of chondrules of the cut and polished surface and 4279-4626×10-5 SI within the uncut original surface.

Petrography: (A. Irving and S. Kuehner, UWS) The specimen consists of relatively small, round chondrules (0.8±0.3 mm, some up to 2.1 mm) in a recrystallized matrix rich in stained metal. Primary minerals are olivine, orthopyroxene, clinopyroxene, sodic plagioclase, chromite, merrillite, chlorapatite, troilite and kamacite (partially altered to iron hydroxides).

Geochemistry: Olivine (Fa18.6-18.9, N = 3), orthopyroxene (Fs15.8-16.3Wo1.1-1.2, N = 3), clinopyroxene (Fs5.7-5.8Wo45.6-46.4).

Classification: Ordinary chondrite (H4).

Specimens: A total of 13700 g of material (including the main mass) at BajaAO; one polished thin section at UWB.
