Description
The Late Palaeozoic rock associations, in particular A-type igneous rocks, of Iran are rarely exposed, but they are key to reconstructing the evolutionary history of the Tethyan oceans. Zircon U–Pb dating of a representative rhyolite sample from Pir-Eshagh, NW Iran, yields an Early Carboniferous (Visean) crystallization age of 340 ± 2.7 Ma. The extrusive rhyolite has the chemical characteristics of the A1 subtype of A-type magmas, providing evidence for a magmatic activity within extensional...[Show more]
