Rock coast morphology in relation to lithology and wave exposure, Lord Howe Island, southwest Pacific

Abstract:
The morphology of rock coastlines appears primarily to be a function of the eroding force of waves and the resistance of rocks, but a number of local factors complicate determination of the relative significance of these as opposed to other factors. Lord Howe Island, a small, basaltic mid-oceanic island in the northern Tasman Sea, presents a unique opportunity to differentiate the roles of rock resistance and wave exposure. The island occurs at the southern limit of coral growth and there is a fringing coral reef and lagoon on a portion of the western coastline. The reef markedly attenuates wave energy and there is an impressive contrast between the sheltered lagoonal coastline, which consists largely of depositional sandy beaches and vegetated hillslopes, and the exposed coastline which is bold and rugged having been eroded by waves into precipitous plunging cliffs, cliffs with talus slopes, and cliffs with basal shore platforms. There is a clear contrast between the development of basalt shore platforms along the sheltered and exposed coastlines: exposed platforms are wider, backed by a higher and steeper cliff, and are without talus deposits, as opposed to sheltered platforms that are veneered by talus. Calcarenites, deposited in the Late Pleistocene, hence precluding significant rock coast inheritance, have been eroded into platforms that are approximately twice as wide on the exposed coastline than the sheltered coastline. Further evidence as to the efficacy of wave erosion around Lord Howe Island is provided by a suite of landforms that appear to have developed as a result of localised wave-quarrying of highly jointed dykes (sea caves, arches, blowholes, and gulches)
