An isolated olistolith in the CiucaÅŸ Conglomerates (Albian, Carpathian Bend) Essay on sedimentogenetic significance

Abstract

In the eastern part of the CiucaÈ™ Mountains (Carpathian Bend area) an 18 m long limestone block was located. Unlike the numerous Albian Bucegi olistoliths included in shallow-waters shelf sediments, this is the first olistolith identified in the Albian deep sea fan sediments from the Carpathian Bend area. Structureless rudites are embedding the CiucaÈ™ olistolith, suggesting that rudites and olistolith were transported together due to sediment gravity flow processes. Two CiucaÈ™ olistolith provenance hypotheses are discussed including a local or a distal source area.
