Description :
This study assesses the future long term stability of the Ranger Uranium Mine area by examining the past (Quaternary) evolution of landforms in the vicinity of the mine. Five categories of geomorphological stability are recognised on the basis of the type and intensity of past and present geomorphological (erosional/depositional) processes. The oldest land surfaces are judged to be the most stable and consequently the best suited as sites for rehabilitated structures, as they have survived Holocene and Pleistocene climatic and eustatic sea level changes. The youngest landforms have undergone extensive change over relatively recent periods and are unsuitable as sites for rehabilitated structures.
