Rusalka 52.42861°N, 16.86583°E
- Poznan, Poland
- Find: 2016 Mar
- Classification: Ordinary chondrite (L4)
History: A fresh meteorite sample of 816 g was found March 2016 in the forest/park at Lake Rusalka (near Poznan, Poland) by an anonymous finder, but was unrecognized as a meteorite until late 2018.
Physical characteristics: The meteorite has a dark appearance with a well-preserved fusion crust.
Petrography: (A. Bischoff, IfP). The rock is an ordinary chondrite. It has a chondritic texture, with well-defined chondrules with a size of about 500 µm. The metal is well-preserved, but partly shows thin rims of typical terrestrial alteration products. The weathering degree is W1. The rock is weakly shocked with olivines having planar fractures (S3).
Geochemistry: Mineral compositions and geochemistry: (K. Klemm and A. Bischoff, IfP). The rock has equilibrated olivine (average: Fa22.6±0.7; n = 10). Low-Ca pyroxene (average: Fs17.9±2.2; (n = 9)) shows some variation in composition (range: Fs13.9-19.7) typical for type 4 ordinary chondrites. The analysis of the oxygen isotopes (A. Pack, UGött) indicates an L chondrite heritage (δ18O=5.32‰, δ17O=3.51‰; Δ17O=0.74‰). The composition has been affected by terrestrial alteration. Cosmogenic radionuclide concentrations have been analyzed (M. Laubenstein, LNGS) by means of nondestructive high purity germanium (HPGe) gamma spectroscopy in spring 2019. Of the medium and long-lived cosmogenic radionuclides only 22Na and 26Al were positively identified. From the data, it was calculated that the meteorite probably fell about 12 (±2) years ago.
