A global geologic map series of Mars was digitized at high resolution (1.846 sq km/pixel). It was found that the surface of Mars is predominantly volcanic. A resurfacing history was constructed by estimating the total extent of the geologic units. Eolian resurfacing was prevalent during the Late Amazonian Epoch, affecting 4.9 x 10 to the 6th sq km. It was found that resurfacing rates vary according to the absolute-age scheme used and generally decrease with time. Resurfacing rates were approximately 1000 sq km/yr during the Middle Noachian Epoch, one hundred to several hundred sq km/yr during the Late Noachian to Late Hesperian Epochs, and tens of sq km/yr or less during the Amazonian Period.
