%X Small oil deposits located in Kor¨¾a near the town of Turzovka in north-western Slovakia and other small deposits located in the Mikov¨¢ region of northern-eastern Slovakia were the first oil deposits discovered and exploited in these parts of the Western Carpathians. Small volumes of oil, natural gas and water rises to the surface on a northern slope in Kor¨¾a and several tenths of metres further on these descends into the soil cover and entered the local Kornianka creek. Kor¨¾a and its broader surrounds are geologically part of the Magura Nappe of the Carpathian Flysch Belt. The preliminary gas chromatography results indicate weakly biodegraded mature oil with a prevailing aliphatic hydrocarbon fraction. Weak biodegradation and continuous outflow over 100 years following its discovery in 1901 indicate its connection with a deeper oil reservoir. Although methane is the dominant component of this natural gas, the presence of higher gaseous hydrocarbons with the methane carbon isotopic composition indicates a methane gas associated with the main stage of oil generation.
