| Summary: | The Eastern Mediterranean Basin is notable for recent discoveries. However, limited data and knowledge about petroleum system elements, especially source rocks in the Western Taurides, pose challenges for hydrocarbon exploration. This study conducted a detailed investigation of Early Silurian, Early Triassic, and Middle-Late Miocene sections in the Western Taurides. Geochemical analyses combined with sedimentological, stratigraphical and regional geological interpretations of 290 outcrop samples and 17 samples from the DL-1 well revealed significant source rock potential. Early Silurian Güneyyaka section samples, rich in type-II kerogen, are mature and classified as good to excellent source rocks. Their extracted hydrocarbons resemble those from the Dadaş-I member, indicating an extension of the Early Silurian hot shale deposit beyond the Diyarbakır Basin. The Post-Ordovician transgression and subsequent upwelling processes, which generated anoxic conditions, are highlighted as the driving mechanisms behind the formation of the Güneyyaka source rock samples. Kesmeboğaz samples, which are spent source rocks, underwent diagenetic/metamorphic processes, providing a typical Early Silurian profile. Early Triassic samples, rich in type II/IIS kerogen, were deposited in an anoxic/sulfidic shallow marine environment and are excellent source rocks, emphasizing the role of rift-created asymmetrical basins with water column and climatic conditions of Late Smithian. Middle-Late Miocene Beydiğin and Oymapınar sections are fair to good source rocks with type II/III kerogen. Inorganic carbon and oxygen isotope analyses of Globigerina samples from Beydiğin reflect ice sheet dynamics and restricted Atlantic-Eastern Mediterranean water flow, with the Middle Miocene Thermal Maximum being key drivers of source rock generation. Doğu Akdeniz Havzası, son keşiflerle dikkatleri üzerine çekmektedir. Ancak, Batı Toroslar'daki petrol sistemi elemanları, özellikle kaynak kayalar hakkındaki sınırlı veri ve bilgi nedeniyle hidrokarbon ...
