Abstract
Planktonic Foraminiferal Biostratigraphy of Tanjero Formation (Late Maastrichtian) in Bekhme Area, Northeastern Iraq
Highlights
The studied section is located at the northern limb of Perat anticline 45 km northeast of Aqra city
The lower contact of the Tanjero Formation is gradational and conformable with Shiranish Formation (Late Campanian -Early Maastrichtian), while its upper contact is unconformable with Kolosh Formation (Paleocene) (Figs.3&4)
BIOSTRATIGRAPHY The investigation of foraminiferal assemblages within the studied section revealed that planktonic species are abundant in general within all the sequences of Tanjero Formation
Summary
The studied section is located at the northern limb of Perat anticline 45 km northeast of Aqra city. The Tanjero Formation was first defined by (Dunnington, 1952 in Bellen et al.1959) from the highly folded zone of northern Iraq, its type section located at Sirwan vally, 2 km to the south of Kani Karweshkan village, near Halabja town (Fig.1), on the right bank of Sirwan River (upstream of the Dialla River). The lower contact of the Tanjero Formation is gradational and conformable with Shiranish Formation (Late Campanian -Early Maastrichtian), while its upper contact is unconformable with Kolosh Formation (Paleocene) (Figs.3&4)
