“…This paper investigates rates of coastal denudation of greenschist in the supratidal zone on the Start-Prawle peninsula in south Devon, United Kingdom (Figure 1). The nature of the rock weathering processes operating in the study location is indicated by the abundance of honeycomb weathering patterns on exposed surfaces; these features are commonly regarded as indicative of weathering by salt crystallization (Bartrum, 1936;Mustoe, 1982Mustoe, , 1983McGreevey, 1985a;Butler and Mount, 1986). Studies by the present author (Mottershead, 1981(Mottershead, ,1982(Mottershead, ,1983 have demonstrated that rock denudation is indeed active, with a mean rate of surface lowering derived from 34 points over a one year period measured by micro-erosion meter (MEM) of 0.61 mm a-'.…”
