Święcany                    49°4729’’ N, 21°1528’’E

Jasło, Poland

Find: September 2004

Ordinary chondrite (L/LL5)

History: A girl of age 12, Katarzyna Dępczyńska, found the stone in gravel on a road about 100 m from the house no. 73 in the village of Święcany, Jasło district, Podkarpackie province, Poland. The gravel was probably brought from a quarry near Skołyszyn in 2003. The stone was then given to Mr. Marcin Mazur from the town of Jasło, who gave it for examination to Mr. Łukasz Bandur, student of geology, who found it was a chondrite. Then the stone was given for classification to Dr. Łukasz Karwowski USil.

Physical characteristics: It is an 8 g rusty stone with tiny grains of quartz and argillaceous slate stuck to its surface and rare fragments of fusion crust.

Petrography: (Ł. Karwowski USil) Metallic Fe-Ni is replaced by iron oxide except a few tiny taenite grains. Troilite is largely weathered. Iron hydroxides and the remaining metal and troilite comprise 5–6 vol% No alteration of silicates. There are few well-delineated chondrules and many chondrule fragments. Matrix is composed of olivine and pyroxene grains, some of which are quite large, comparable with chondrules in size (up to 1.5 mm). The stone is brecciated.

Mineral compositions: Olivine (Fa25.3–26.4), low-Ca pyroxene (Fs22.0–22.8), high-Ca pyroxene (Fs7.0–7.0 Wo46.5–46.5), feldspar (An10.4–13.9 Or4.4–6.3).

Classification: Ordinary chondrite (L/LL5); S2, W3.

Type specimens: One thin section and the main mass, 6.62 g, are on deposit at USil.
