new meteorite from Poland
ordinary chondrite H5 - Opis:
- An anonymous person from Częstochowa in Poland found a new meteorite during the summer of 2008. The specimen was found in eolian sand, where exotic grains connected with glacial activity were not observed. The suspected meteorite was kept in the founder’s possession until the autumn of 2018. This was when the holder of the meteorite contacted the owners of the woreczko.pl webpage, which is dedicated to meteorite identification. Moreover, the webpage was developed and operated by meteorite collectors Jan Woreczko and Wadi. After meeting, Jan and Wadi bought the meteorite, which is now part of their collection. After the meeting, Jan and Wadi bought the meteorite (total meteorite mass 2143 g), which is now part of their collection. Three fragments with their total mass 20.74 g as well as two thin-sections (7.03 g) are deposited at the Earth Sciences Museum, University of Silesia in Katowice. The fusion crust is black to brownish, typical for a chondrite. Regmagliptes are visible. The meteorite is characterized by chondrules, which range in diameter from 0.015 to 1.000 mm in diameter. The most common type of chondrule is represented by olivine (Ol). The barred Ol texture, showing elongate, sub-parallel bars of olivine with clear pyroxenes (Px) and oligoclase between the bars. The second characteristic type is represented by Ol-Px porphyritic chondrules and radial Px chondrules. The matrix is not recrystallized; and the clasts are up to 0.1 to 0.2 mm in diameter. Px and Ol, plagioclase, metallic phases, troilite, and spinel (Cr-spinel) are up to 71.9 vol.%, 11.2 vol.%., 7.0 vol.%., 4.2 vol.%., and 1.1 vol.% of the meteorite, respectively. The average content of the secondary minerals is 4.4 vol.% (close to the outermost part is up to 8–10 vol.%. The meteorite is classified as a H5 ordinary chondrite, based on the Ol and Px composition (Fa/Fs), with an official name ‘Kuźnica’.
