The field is located in north-western Turkey, 80 km south of the city of Canakkale and 5 km from the Aegean Sea.

The Tuzla Volcanics, representing the most widespread volcanic unit of the Oligocene-Miocene, consist predominantly of hydrothermally altered porphyritic andesites, basaltic–andesitic lavas, and associated pyroclastic deposits. These units are exposed around Babadere, Naldöken, Taşboğaz, Çamköy and Kestanelik and are intruded at depth by the Kestanbol Pluton. The volcanic succession is subdivided into three principal units: (i) Oligocene-Early Miocene felsic lava flows (rhyolite–dacite), characterized by massive, hard, and brittle flows locally associated with flow breccias. These rocks display colors ranging from grey to greenish and reddish-brown, and well-developed joint and fracture systems are common. (ii) Lava–pyroclastic alternations composed of well-bedded pumice and crystal tuffs, volcanic blocks, and bombs. These units are commonly affected by hydrothermal alteration, resulting in yellow, light brown, or cream-colored hues. (iii) Later-stage andesitic–trachyandesitic lava flows, locally intercalated with flow breccias, lahar deposits, and lacustrine sandstones.
