Research included the identifica­ tion of source rocks, genelic characteri za tion of hydro­ carbons within accumul ati ons, detennina tion of alter­ ation and destruction of hydrocarbons within reservoirs and ex planation of the mechanisms for the appearance o f high concentrations of chem ica ll y inorganic con- 192 KAAlOVAC KAAPINA ZAGREB @ CA)(OV~C VAAiIZOlN % SISAK - '<9l..~ KO~IVN1tA ~~, VII'!OVITICA ® POtEGA ® LEGEND _ OIlFIELD .,.	cache/gc-352.pdf	txt/gc-352.txt
