Description :
The geology of the island is varied, with hard and resistant basalt lavas, breccias and tuffs of intermediate resistance, and highly erodible eolianites. This variability provides an excellent opportunity to examine the influence of rock resistance on the development of the spectacular rock coast landforms that occur around the island. Relative rock resistance was assessed through a combination of Schmidt hammer data, and statistical analysis was undertaken to remove outlying values. The paper considers the possibility of landform inheritance and examines the distribution of resistant plunging cliffs and erosional shore platform.
