Writeup from MB 100:
Sołtmany 54°00.53’N, 22°00.30’E
Fell: 2011 Apr 30, 6:03 CEST
Classification: Ordinary chondrite (L6)
History: At 6:03 CEST, April 30, 2011, a stone penetrated the edge of a roof and onto a concrete step at a farm in the village of Sołtmany, Poland. It was immediately found by the owners of the farm, alarmed by loud noise. Mr. Roman Rzepka from the nearby town of Giżycko, recognized the stone as meteoritic, and informed scientists. On May 2, fragments of the stone were purchased and distributed among laboratories for examination.
Physical characteristics: The meteorite was broken by the impact into 813 g, 155 g and many smaller pieces. Later the main mass was broken by the finder. Total mass is at least 1066 g. Most pieces have 1-1.5 mm thick fusion crust. The crust is of the same thickness all around the meteorite, what suggests the stone was a single fall. The hole in the roof and the trace of impact onto the step below showed that the fall was nearly vertical. Internally, the stone is nearly white, with clearly visible troilite and FeNi grains (to 3 mm), dispersed uniformly throughout the meteorite. Only a few chondrules are visible.
Petrography: (Łukasz Karwowski, USil) Chondrule and matrix olivines and pyroxenes show homogeneous compositions. Low-Ca pyroxene is usually accompanied by Ca pyroxene. In larger grains of feldspar albitic twinning is visible. Sparse chondrules (to 2 mm) are well crystallized and lack glass. There is accessory F-Cl-bearing apatite. Opaque minerals are represented by troilite, kamacite, taenite, and rare chromite. Small grains of copper are visible in taenite grains.
Geochemistry: Olivine Fa25.6; low-Ca pyroxene Fs21.9Wo1.5; high-Ca pyroxene En46.6Fs8.8Wo44.6; feldspar Ab85Or5An10; kamacite Fe 95.87, Ni 5.23, Co 0.74 wt%; troilite Fe 50.23, S 49.69 wt%. Accessory: chromite, Fe-Cl apatite, metallic Cu in taenite.
Classification: Equilibrated ordinary chondrite (L6), W0, S2.
Specimens: 65g at USil (type specimen). Also 120 g at UTWroc.
