Geology Colloquium | Spatial and Temporal Variation of Continental Extension in Iran, Oct. 26

Ahmadreza Malekpour-Alamdari

The Geological Sciences Colloquium Series presents Ahmadreza Malekpour-Alamdari on “Spatial and Temporal Variation of Continental Extension in Iran: a Preliminary Synthesis” on Oct. 26 at 2 p.m. in Clippinger 205.

Ahmadreza Malkepour-Alamdari is a Visiting Assistant Professor in Geological Sciences.

Abstract: During the last twenty years, several metamorphic core complexes have been recognized in the Iranian Plateau. These structures accommodate tens of kilometers of crustal extension. The timing of extension in these regions varies from the Late Cretaceous to the Oligo-Miocene. Understanding the mechanism of extension in these extensional domains is essential for understanding the tectonic evolution of the Iranian Plateau.  However, the relationship of these extensional terrains to each other and their effects in the shaping of the plateau are poorly understood. I will present new 40Ar/39Ar thermochronology data from each domain and will discuss the role of this extension in the structural and magmatic evolution of the entire Iranian Plateau.

Upcoming Colloquia

Dawn Ruth of Ohio University Geological Sciences on “Open Questions on Open Vent Volcanoes: Case Studies of Llaima (Chile) and Mayon (Philippines)” on Nov. 30 at 2 p.m. in Clippinger 205.
