History: A single stone was found by L. A. Belov while collecting mushrooms between the city of Kirishi and the Pchevo village.

Physical characteristics: A single 1350 g angular, friable, dark gray fragment partially covered with shiny black fusion crust.

Petrography (D. D. Badjukov, Vernad): Chondrules have sharp boundaries with the matrix and range in apparent diameter from 0.15 to ~ 3 mm, with an average of 0.42 mm. Metal content is 2.6 vol.%. Matrix is clastic, consisting of distinct mineral fragments.

Geochemistry: Mineral compositions: Homogeneous olivine (Fa24.5±0.3), low-Ca pyroxene (Fs2-26), high-Ca pyroxene (Fs4-15Wo32-49), chlorapatite. Some chondrules contain bytownite (An70-77). Opaques include kamacite (4.5-6.5 wt% Ni, 1 wt% Co), taenite (28-50 wt% Ni, 0.2-0.4 wt% Co, 0.2-0.4 wt% Cu), Cu metal, troilite, chromite (Cr/[Cr+Al] = 0.95), ilmenite.

Classification (D.D.Badjukov, A.I. Ivliev, Vernad): Ordinary chondrite (L4), S1, W0.
