The Tendürek Mountain range is a volcanic mountain range located in eastern Turkey, near the Iranian border. It is an important geological feature of the region and has been the subject of many studies due to its unique features.

The volcanic rocks found in the Tendürek Mountain range are primarily andesitic to dacitic in composition, with some rhyolitic rocks also present. These rocks are characterized by their high silica content and the presence of large phenocrysts of plagioclase and hornblende. The rocks are also highly porphyritic, with large crystals (phenocrysts) embedded in a finer-grained matrix.

The volcanic rocks in the Tendürek Mountain range also have a unique geochemistry, with high concentrations of rare earth elements (REEs) and other trace elements like thorium, uranium, and zirconium. This unique geochemistry is thought to be related to the tectonic setting of the mountain range, which was formed during the collision of the Eurasian and Arabian plates.
