A fossil proof for the origin of the Hirnantian glaciomarine record in Bulgaria: A preliminary result

Review of the Bulgarian Geological Society
The Sirman Formation in the Svoge Unit is built of Hirnantian diamictites, a product of the Gondwana glaciation at the end of the Ordovician. One subangular lonestone of light gray sandstone of size of about 1 cm was found in the lower part of the formation.
