Basement rock reservoirs are a special type of oil and/or gas reservoir, which has been usually neglected until recently as a target for exploration. In this study, it is aimed to investigate the oil and gas potential of Niğde Massif by conducting TPH analyses on the samples taken from the natural cold-water resources in the massif and its surroundings. As a result of the analyses conducted, hydrocarbons have been detected in all the water samples. The n-alkane hydrocarbons found in the water samples are the mature petroleum hydrocarbons, which are the geochemical evidence for a working petroleum system in the study area. The dom structures in which they are suitable to be entrapped and protected for hydrocarbons in a predominantly SW-NE orientation, and determined by gravity and magnetic maps which are entirely in a harmony with each other, where metamorphic rocks in which granite has been located in its center have formed, is the possible oil and/or gas reservoir in the investigation area. The geochemical exploration methodology used in this study may be a new method that can eliminate the discovery of hydrocarbons in the metamorphic massif and granitic rocks by chance.
