Unconsolidated Sediments

The unconsolidated sediments are deposits which were formed by secondary sedimentation of previously weathered rocks and redeposition of their fragments, and/or by chemical and biochemical precipitation from solutions. They were not compacted and lithified. Unconsolidated sediments are mostly of Tertiary and Quaternary ages. However, there are some exceptions, as the Cambrian blue clays of St. Petersboug with their important fossils (gastropods, hyolithids, spores).
