ABSTRACT:
This paper discusses
the biostratigraphy and palaeoecology of calcareous
nannofossils of the uppermost Mozduran Formation in the Jozak section in west Kopet-Dagh
basin. The Mozduran Formation consists of white to grey
Limestone. In the studied sections, samples are taken and prepared with smear slides. In the Jozak section, 17 species have been determined.
Based on nannoplanktons and as a result of biostratigraphy studies, the nannofossil
standard zones (CC4) are identified. According to this zone, the age of the studied thickness
is Early Hauterivian in
this section in west Kopet-Dagh basin. The presence of warm water indicators (Nannoconus, Watznaueria, Lithraphidites)
suggests warm surface water conditions in the studied thickness.
In the Jozak section based on Nannoconus spp., low fertility conditions are suggested. The studied area is deposited in low to middle latitudes and
shallow marine environments.
