biostratigraphy and paleoecology of cretaceous/tertiary boundary in ...

Chapter one
Introduction
The Tanjero Formation underlies the Red Bed Series directly; Numan
(2000) and Karim (2004) regarded the basin of latter formation and Kolosh
Formations as Zagros Early Foreland Basin. In the Tagaran, Qala Cholan,
Qishlagh, Sura Qqalat and Mawat area, the Tanjero Formation overlied by
Red Bed Series graditionaly. Lawa et al., (1998), Karim (2004) and
Sharbazheri, (2007). mentioned that the contact is gradational in some places
and unconformable in others.
Even as in the other three studied sections (Sirwan valley, Dokan and
Smaquli Gali sections), the Tanjero Formation underlies directly the Kolosh
Formation, and the nature of the contact explained briefly in subsequent
chapters.
1.4- General stratigraphy
The general stratigraphy of the Cretaceous/Tertiary boundary of Upper
Campanian-Maastrichtian and Paleocene-Lower Eocene cycles of the studied
sections was shown in Fig (1.2), the studied sections in the Sulaimani area
