Göllüdağ is a complex of lava domes with related cinder cones, between Hasan Dağ and Acıgöl in Central Anatolia. The lava domes and cinder cones overlie the Tertiary-age Derinkuyu caldera. Activity is dominantly rhyolitic to rhyodacitic, with extensive obsidian deposits. The obsidians are dated from 1.33 to 0.84 million years (Bigazzi et al., 1995). Numerous cinder cones have formed along N-S fissures north of Göllü Dag and south of the Erdas Dag massif.

There are Domes of Büyük Göllüdağ and Küçük Göllüdağ at the top of the volcano. 0.4my K / Ar ages from Küçük Göllüdağ, 1.1my from Kaletepede, 0.8my from Büyük Göllüdağ (Mouralis et al., 2019).

Keller (1980, in GVP) considers some cinder cones to have formed in the Holocene due to their fresh appearance, and hydrothermal alteration and hot springs suggest that the area is still active.
