Salt formations exist in Kızılırmak Graben (Central Anatolia, Turkey), which consists of volcano-sedimentary units, and it was stated in previous studies that these formations have a diapiric structure. The adjacent basin, Ayhan Basin, contains bituminous shale and operated coal deposits. For this reason, in this study, it is aimed to investigate the oil and gas potential of the Kızılırmak Graben by conducting TPH (Total Petroleum Hydrocarbons) analysis on the samples taken from natural cold-water resources by making use of the thought that hydrocarbon generation may come into existence from those units in the Ayhan basin. As a consequence of the analyses performed, hydrocarbons have been brought into the open in all the water samples. The organic geochemical methods have been used to find out the source of hydrocarbons determined in the water resources. The disclosed n-alkane hydrocarbons are the mature petroleum hydrocarbons derived from peat/coal type organic matter (Type III kerogen, gas-prone). These mature hydrocarbon-rich waters can be regarded as evidence for the availability of a working hydrocarbon system associated with possible salt diapir identified by using gravity and magnetic data obtained from the investigation area.

In the northern part of the Niğde (Central Anatolian) Quaternary Bor Basin, stratigraphic sections P1 and P2 were sampled, reaching depths of 11 m and 25 m. The samples were analyzed with thin-section, XRD, and chemical analyses (ICP-MS) to determine their chemical and mineralogical properties. In the study area, partially lithified volcano-sedimentary rocks comprised paleosol, calcrete, gravel, sand, silt, mud, clay, and volcanoclastics such as pumice fall-out. Grain size analyses from the Zengen (P1) and Altunhisar (P2) regions showed very poor sorting and strong positive skewness. The Zengen-area (P1) samples contained rock fragments, calcite, quartz, opal-CT, feldspar, amphibole, pyroxene, biotite, and clay minerals such as smectite, chlorite, illite, palygorskite, and sepiolite. In calcrete zones, however, the amounts of CaO increased, whereas significant decreases in the amounts of SiO2 were observed. Therefore, a negative correlation between SiO2 and CaO was observed. The vertical distributions and behaviors of trace elements in the Zengen-area profile showed variation with the different levels of the P1 section. It is thought that in the Bor Plain, after 17,000 years ago, no lacustrine phase reached a level above the periglacial lake level in the region, reaching this level with the melting of the ice sheets in the area. During the late glacial period, shallow freshwater lacustrine phases and paleosols were identified from 12,500 to 11,000 yr BP in the basin.

Yakın tarihli çalışmalarda, hidrokarbon birikimleri ve altın cevherleşmeleri arasındaki bağlantılar incelenmiştir. Bu çalışmalardan elde edilen sonuçlara göre, altın ve hidrokarbonların aynı hidrotermal akışkanlar tarafından taşındığı ve çökeltildiği tespit edilmiştir. Seferihisar Yükselimi’nde, Türkiye’nin kanıtlanmış en büyük altın cevheri rezervine sahip Efemçukuru Altın İşletmesi bulunmaktadır. Bu gerekçe ile çalışmada, Seferihisar Yükselimi’nin petrol ve doğalgaz potansiyelinin su kaynaklarından alınan örnekler üzerinde Toplam Petrol Hidrokarbonları (TPH) analizleri yapılarak araştırılması amaçlanmıştır. Yapılan analizler sonucunda, su numunelerin tamamında hidrokarbonlar tespit edilmiştir. Sularda tespit edilen hidrokarbonların kaynağının belirlenmesi için organik jeokimyasal yöntemler kullanılmıştır. Su numunelerinde belirlenen n-alkan hidrokarbonlar, olgun petrol hidrokarbonlarıdır. Bu olgun petrol hidrokarbonları, çalışma alanında çalışan bir petrol sisteminin varlığı için jeokimyasal bir kanıttır. Olgun hidrokarbonlarca zengin suların varlığı nedeniyle, gravite ve manyetik verilerine göre çalışma alanında belirlenen maksimum 765 m derinliğindeki yapının bir petrol ve/veya doğalgaz rezervuarı olma potansiyeli oldukça yüksektir.
