Geochemistry and source characteristics of Dehsard mafic volcanic rocks in the southeast of the Sanandaj–Sirjan zone, Iran: Implications for the evolution of the Neo-Tethys Ocean

The Late Jurassic–Early Cretaceous Dehsard mafic volcanic rocks crop out in the southeastern Sanandaj–Sirjan Zone (SSZ), composed primarily of basalts and basaltic andesite with subordinate dolerite. They are influenced to some degree by hydrothermal alteration under zeolite–greenschist facies.
