The Durmuştepe deposit formed as a proximal volcano-sedimentary hydrothermal-exhalative system, shaped by rapid mixing of low- to medium-temperature hydrothermal fluids from the ophiolitic basement of the Maden Complex with oxic seawater and by contemporaneous sedimentation. The Hazar Group, which transgressively overlies the Guleman Group, generally consists of a sandstone–shale–marl–limestone alternation. Conglomerates occur at the base of the unit, passing upward into sandstone, mudstone, claystone, marl, argillaceous limestone, silexite, radiolarite and pink-to-red limestones. This fossiliferous unit, referred to as the ‘lower flysch’, also contains volcanic intercalations such as basalt, diabase, melaphyre, tuff and andesite.
The Maden Complex covers a broad tectonic zone that extends in an approximately NE–SW direction, parallel to the East Anatolian Fault (EAF). This zone extends from the northern parts of the Palu and Arıcak districts in the east to the south of Malatya and the northern parts of Adıyaman. The Maden Complex shows more extensive outcrops in the southern parts of the fault between Palu and Lake Hazar, whereas from the southwest of Lake Hazar onward it becomes dominant in the northern blocks of the fault.
The Maden Complex in the study area shows a lithologically highly heterogeneous structure. The unit generally consists of red, green and grey silicified mudstones, maroon limestones with volcanic intercalations, a sandstone–shale–marl alternation, conglomerates, green limestone blocks, and basalts and/or spilites. The ferruginous manganese (Fe–Mn) mineralizations examined here also crop out, like the other volcanic and sedimentary units, directly as part of the lithological assemblage within the Maden Complex.
