Writeup from MB 105:

Kölked        45.96°N, 18.69°E

Baranya, Hungary

Find: March 2016

Classification: Ordinary chondrite (H5)

History: In early March 2016, an anonymous individual found the stone buried at a depth of approximately 40 cm in wet soil, in a moorland, between the town of Mohács and the village of Kölked. The stone was sent to Zsolt Kereszty who measured its specific gravity (3.16 g/cc), noted strong attraction to a magnet, and observed chondrules in a cut surface.

Physical characteristics: A single stone with no fusion crust, reddish-brown oxidized surface. Saw cut reveals numerous, densely packed, small chondrules set in an orange-brown matrix.

Petrography: (C. Agee, UNM) This meteorite has many equilibrated chondrules, a relatively high porosity, and much of the metal has been oxidized. Barite weathering product was detected.

Geochemistry: (C. Agee and M. Spilde, UNM) Olivine Fa17.0±0.3, Fe/Mn=36±2, n=31; low-Ca pyroxene Fs15.1±0.2Wo1.4±0.2, Fe/Mn=21±1, n=13; augite Fs4.6Wo46.2, Fe/Mn=13, n=1.

Classification: Ordinary chondrite (H5)

Specimens: 22.1 g on deposit at BajaAO, 2.2 g including a probe mount at UNM, ZKereszty holds the main mass.
