Yöredeki doğal gaz emareleri Antalya naplarının bir bileşeni olan ve ileri derecede serpantinleşmiş Tekirova peridotit napının batı bölümünde yer alır.  Antalya napları Kumluca bölgesinde Beydağları kireçtaşlarının yanı sıra Kasaba-Finike havzasını dolduran Paleojen – Neojen yaşlı denizel tortulları çok katlı bindirmeli bir dokanakla üzerler. Finike havzasını dolduran Paleojen - Neojen yaşlı tortullar yaşları Eosen ile Erken-Orta Miyosen arasında değişenı kırıntılı ve karbonatlı tortul bileşenlerinden oluşur. Miyosen istifinin en alt bölümünde yer alan Akitaniyen yaşlı karboanat kayalar, büyük bölümü ile resifal özellik gösteren kalın katmanlı mercanlı kireçtaşlarından yapılıdır. Finike yöresindeki kalınlığı 300 metreye ulaşan Akitaniyen (Erken Miyosen) yaşlı resifal kireçtaşları, yansıttıkları gözenekli doku nedeniyle mükemmel bir rezervuar kaya özelliğine sahiptir. Finike havzasında Akitaniyen kireçtaşlarını uyumlu bir dokanakla üzerleyen Burdigaliyen yaşlı tortullar egemen olarak şeyl, karbonlu şeyl, çamurtaşı ve bunlara eşlik eden türbiditik tortullardan yapılıdır. Burdigaliyen istifinin altında bulunan ve karbonlu şeylden oluşan ince taneli tortul bileşenler, bu istifin çok iyi derecede ana kaya ve örtü kaya özelliklerine sahip olabileceğini göstermesi bakımından önemlidir.Finike havzasını dolduran tortulların stratigrafik konum, bileşim ve doku özellikleri göz önüne alındığında, Çıralı yöresindeki doğalgaz emarelerinin daha çok allokton birimlerin altında yer alan Erken-Orta Miyosen yaşlı Paleojen - Neojen tortullarından türediğini ve biyotik kökene sahip olabileceğini belirtmek mümkündür. Diğer taraftan, Doğu Akdeniz bölgesinde günümüze dek bulunan doğal gaz yataklarının tümünün Miyosen yaşlı denizel tortul istif içinde yer almış olması, bu tezimizi destekleyen en önemli veri olarak değerlendirilebilir.</p></abstract>

                            <p>Natural gas seeps known as Chimaera -Yanartas, found in the Antalya-Çıralı region, are one of the most important hydrocarbon seeps known in the Eastern Mediterranean Region. Natural gas seeps in the region are located in the western part of the highly serpentinized Tekirova peridotite nappe, which is a component of the Antalya nappes. The Antalya nappes overlie the Beydağları limestones in the Kumluca region, as well as Tertiary marine sediments filling the Finike basin, with multiple thrust contacts.Tertiary sediments filling the Finike basin consist of clastic and carbonate sedimentary components ranging in age from Eocene to Early-Middle Miocene. The Aquitanian carbonate rocks located at the bottom of the Miocene sequence are mostly composed of thick-layered coral limestones with reef characteristics. Aquitanian reefal limestones in the Finike region, with a thickness of up to 300 meters, have excellent reservoir rock properties due to their porous texture.Burdigalian sediments, which overlie the Aquitanian limestones with a concordant contact in the Finike basin, are predominantly composed of shale, carbonaceous shale, mudstone and accompanying turbiditic sediments. The organic matter-rich sedimentary content of the Burdigalian sequence and the accompanying turbiditic components are important as they indicate that this sequence may have very good source rock and cover rock properties.Considering the stratigraphic position, composition and texture of the sediments filling the Finike basin, it is possible that the natural gas seeps in the Çıralı region are derived from the Early-Middle Miocene Tertiary sediments located under the allochthonous units and may have biotic origin. The fact that all the natural gas deposits found in the Eastern Mediterranean region up to the present day are located in the Miocene marine sedimentary sequence can be considered as the most important data supporting this thesis.</p></trans-abstract>
