AB  - Bu çalışma, Mamak (Ankara) bölgesinin jeokimyasal çalışmalar, tektonik ve jeofizik veriler ile petrol ve doğalgaz potansiyelinin değerlendirilmesi için yapılmıştır. Çalışma, üç aşamada yürütülmüştür. Birinci aşamada, literatürden çalışma alanının jeolojik özellikleri incelenmiştir. Böylece, jeokimyasal analizler ve jeofizik veri değerlendirmeleri için gerekli olan jeolojik veriler derlenmiştir. İkinci aşamada, çalışma alanının manyetik ve gravite haritaları hazırlanmıştır. Jeolojik ve jeofizik verilerin birlikte değerlendirilmesi sonucunda, çalışma alanında petrol kapanı olabilecek bir yapı belirlenmiştir. Üçüncü aşamada, belirlenen bu yapı üzerindeki ve çevresindeki çeşmelerinden (hayratlardan) alınan su numunelerinde Toplam Petrol Hidrokarbonları (TPH) analizleri yapılarak belirlenen yapının petrol ve doğalgaz potansiyeli değerlendirilmiştir. 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 kanıttır. Olgun petrol hidrokarbonları içeren suların varlığı nedeniyle, gravite ve manyetik verilere göre çalışma alanında belirlenen maksimum 330 m derinliğindeki yapının bir petrol ve/veya doğalgaz rezervuarı olma potansiyeli oldukça yüksektir.

N2  - This study is made to evaluate the oil and gas potential of the Mamak (Ankara) region with geochemical surveys,  geophysical, and tectonic data. The study was conducted in three steps. In the first step, the geological characteristics of the study area from the literature were examined. Thus, the geological data to be required for geochemical analysis and geophysical data evaluations were compiled. In the second step, aeromagnetic and gravity maps of the study area were prepared. As a result of evaluating these data together, a structure that could be a petroleum trap was determined in the study area. In the third stage, total petroleum hydrocarbons (TPH) analyses in the samples taken from the water fountains on and around this determined structure were conducted and the oil and gas potential of the determined structure were evaluated. As a result of this analysis, it has been determined hydrocarbons in all water samples. To determine the source of hydrocarbons in the waters have used organic geochemical methods. The n-alkane hydrocarbons in water samples are mature petroleum hydrocarbons. The mature hydrocarbons are evidence for a working petroleum system in the study area. Due to the presence of waters containing mature petroleum hydrocarbons, the structure in maximum 330 m depth determined in the study area according to gravity and magnetic data has very high potential to become an oil and/or gas reservoir.
