摘要

Fifty-five samples of asphaltites from 12 different veins in (S)lrnak area and two oil samples from Raman and Dinner Oil fields in South East (SE) Turkey have been analyzed by organic geochemical methods (total organic carbon, rock-eval pyrolysis, gas chromatography of saturated fractions, gas chromatography-mass spectrometry and stable carbon isotope). The total organic carbon (TOC) contents in asphaltites ran ged from 12% to 65%. The T_(max)values range between 428 ℃ and 465 ℃. The hydrogen index (HI) values vary between 270 and 531 mg HC/g TOC. The levels of biodegradation of the asphaltites were studied by GC analyses of the saturated fractions and none to moderate biodegradation has been found. Maturity of the asphaltite samples were assessed biomarker ratios provided by GC-MS analysis. Stable carbon isotope ((~13)C) analyses of Raman-Dinner oils produced values about -21‰ and the asphaltene fractions of the asphaltite samples revealed similar values about 26.8‰. It is presumed that the asphaltites are of oil ori gin and has been solidified in veins close to surface and the geochemical correlation and encountering to the oil seeps in crevices suggest similarities between the (S)lrnak area asphaltites and Raman-Dinner oils.
