چکیده

The Taleh-Zang Formation is a predominantly carbonate lithostratigraphic unit that crops out in Lorestan sedimentary basin, southwestern Iran . Lorestan sedimentary basin, formed as a foreland basin in Central Zagros, is characterized by a relatively continuous Cretaceous to Miocene time. In this paper, the microbiostratigraphy of the Taleh- Zang Formation in seven measured stratigraphic sections (Taleh- Zang type section, Kialou, Veisian, Chenar, Ghalebi, Darabi and Chahr Zebr) are is discussed. In all sections, the lower and upper boundaries of the Taleh- Zang Formation with Amiran and Kashkan Formations are conformable. Microbiostratigraphic data mainly based on foraminifera indicate the Middle Paleocene to Late Paleocene for the Taleh- Zang Formation for Veisian and the Early to Late Paleocene at Ghalebi, Darabi and Chenar, the Middle Paleocene for For Chahr Z¹ebr, the Late Paleocene to the Middle Eocence at the type section and the Late Paleocene to Early Eocene at the Kialou section.
