Karacadağ, located in the Southeastern Anatolia region, is a shield type volcano located next to the province of Diyarbakır. Turkey's Iraqi-Syrian border is covered by basaltic lava in an area about the size 200x800km (Lustrino et al., 2010). Karacadağ volcano, which is characteristic with basaltic products, is a volcano typical with its flat topography at this border. Karacadağ, which has a peak height of 1957 meters, is a volcano that started in the Late Miocene and became active in the Quaternary period.


Volcanism, which started in the form of a fissure eruption in the plains in the Late Miocene, spread in the form of a plateau in its early stages, gradually accumulating in the form of a shield and shaped the Karacadağ volcano (Turkecan, 2015). The centers are generally located on northeastern opening cracks (Şaroğlu & Güner, 1981; Şaroğlu & Yılmaz, 1986). Depending on the radiometric studies conducted in the region, Karacadağ volcanism was found to be effective during the Late Miocene, Late Pliocene and Quaternary periods (Haksal, 1981; Ercan et al., 1990; Lustrino et al., 2010)

Although the lava flow age determination shows the middle Pleistocene periods, some lavas seem younger  than this and are thought to belong to the Holocene period.
