Striated boulder pavements can form either on intertidal surfaces in areas affected by floating ice (Martini 1981; Hansom 1983, 1986) or at the base of glaciers or on grounded ice sheets (A.G.I. 1974; Boulton 1978; Visser and Hall 1984). Pavements have also been described from fluvial environments (Mackay and Mackay 1977). Their distinctive nature also allows them to be used in the sedimentary record to assist in the reconstruction of past ice-affected environments (Eyles 1988). Pavements deposited subglacially are argued to be the result of accretion of boulders around an obstacle and to carry striations that are largely unidirectional. Although there are no detailed descriptions of such pavements forming in present glacial environments, they have also been described from the top surface of Quaternary deposits as well as buried within such deposits (Hansom 1983; Eyles 1988). Pavements formed on present cold-climate intertidal surfaces are thought to be the result of abrasion and...
