Late Santonian-Early Maastrichtian calcareous nannofossils from marly deposits near Kerman (Central Iran)
Year
: 2012
Abstract: Abstract For the first time, the calcareous nannofossils of
marly deposits near Kerman (Bardsir area) have been studied.
This study presents the integrated (calcareous nannofossils)
biostratigraphy of the Bardsir section in the Kerman basin,
Central Iran. In most parts of Central Iran, the Upper
Cretaceous sequence is complete and continuous and is divided
into two groups: Cenomanian–Touronian flysch and
Campanian–Maastrichtian flysch. Flyschs composed of sets
of green marl sequences (Coniacian–Santonian) have been
separated to reduce the basin depth and refer to the relative
calm. Bardsir is located 57.6 km from Kerman (Central Iran).
The lithology of this area includes light green marl with layers
of calcareous siltstone, limestone, and flysch rocks. In this
study, 24 samples were taken and prepared with smear slide.
Most species were photographedwith a light microscope. As a
result of this study, 30 genera and 42 species of nannofossils
have been identified. A high-resolution calcareous nannofossil
biostratigraphic study has been carried out, allowing the
division of the studied section into eight biozones of Late
Santonian to Early Maastrichtian age (CC17–CC24).
