GeochemicalMethods to Investigate the Hydrocarbon Seepage Samples in Adiyaman a Southeastern Province of Turkey

Document Type : Original Research Paper



The southeastern part of Turkey is quite rich, fertile and mature in terms of hydrocarbon
seepages. While the use of the related sources meet the energy demand, it damages the environment and human
health. In this study, several geochemical methods were applied to analyze the hydrocarbon sepage samples
obtained from seven towns in the province of Adiyaman where is very close to the oil production areas and
located in the Southeastern part of Turkey. First of all, Total Organic Carbon (TOC), Rock Evil Paralysis, Gas
Chromatography (GC) and Gas Chromatography Mass Spectrometry analyses (GC – MS) were performed
for the samples in question. In the light of these results, oil/bitumen mechanisms, source rock correlations,
formation and migration mechanisms of the related geological environments were found. Then, Inductively
Coupled Plasma Optical Emission Spectroscopy (ICP-OES) analysis of Fe, Al, Mn, Mn, Zn, B, Pb, Ni, Cu
metals were performed. Chemical and mineralogical features of the samples were investigated by IR and
combined with ESR spectra. The samples display typical ESR spectra of Mn+2 ions hyperfine sextet whose
last line was used to check the stones homogenity with respect to manganase content. In this study, heavy
metal pollution and hydrocarbon compounds were determined to damage the environment and several suggestions
were made to overcome the pollution and to enhance the productivity
