The Obukhov Formation is a geologic formation in Belarus and Ukraine that dates to the Late Eocene;[1] the Obukhov Formation is equivalent to the Prussian Formation of Russia.[2]
Rovno amber is found in this formation,[3] and 90% of amber collected from the Obukhov Formation is extracted illegally and the trade is controlled by armed organised crime groups, although the Ukrainian government has begun to oversee excavations since 1993.[3]
