Abstract	The basal plane resistivity of packed pyrolytic graphite was measured as a function of temperature, high hydrostatic pressure up to 1,6 GPa and magnetic fields up to 1 T. Our graphite sample shows a transition from negative magnetoresistivity at some low temperatures to positive one with the temperature growing. Resistivity behaviur suggests for ordering transition about 0,5 GPa. Pressure over the ordering transition suppresses magnetoresistivity of both signs and shifts zero magnetoresistivity point to the lowest temperatures. All of the effects are of elastic character – no change with high accuracy in the resistivity dependencies after unloading to normal pressure can be detected.
