About

Varol Research LLC is the name of the trading company under which Osman Varol offers his services as a independent biostratigraphic consultant specialising in the analysis and interpretation of calcareous nannofossils.

Research

O. Varol PhD and his research associates concentrate their efforts on various aspect of nannopalaeontology including taxonomy, biostratigraphy, palaeogeography and palaeoecology. These research interests either directly or indirectly lead to the improvement and further development of nannofossils as a biostratigraphic tool in the oil industry.

Biostrat

O. Varol PhD devised global and local zonation schemes throughout the stratigraphic column [Jurassic- Recent]. Published zonation schemes include Neogene for South East Asia [1983], Palaeocene [1989] and Paleogene [1998] for the North Sea Area and the Palaeocene for the worldwide use [1989].
