    in order to compare the hydrocarbon generation kinetic parameters (e, a) of source rock and its related asphaltene, an immature core sample from pabdeh formation in gachsaran oil field was studied. artificial thermal maturation of source rock and its related asphaltene was performed by open-system pyrolysis (rock-eval) at three different heating rates of 5, 15, 25 ºc/min. subsequently, the kinetic parameters of the samples were optimized and determined using optkin software. the difference in frequency factor values of the source rock and its related asphaltene is remarkable. however, the activation energy distributions of the studied samples are almost identical. after determining the kinetic parameters of source rock and its related asphaltene, kinetic modelling of the samples was performed using petromod software. the temperatures of the onset (tr 10%) and the peak petroleum generation from studied samples were predicted by the kinetic models. using an assumed geological heating rate of 1.5 ºc/my, the onset of petroleum generation from source rock and its related asphaltene is predicted to occur at around 114 ºc and 103 ºc, respectively. on the other hand, the peak petroleum formation temperature (geologic tmax) is ~136 ºc (tr 56.3%) for source rock, while it is ~132 ºc (tr 57.75%) for related asphaltene.
