“…The inevitability of such mass movement has been noted and observed in specific blanket bog settings (Tallis, 1985), however, it is not generally considered as a limiting process in all settings in which accommodation space is limited or unavailable. The surface of the peat body may also wrinkle, as proposed by Pearsall (1956) and observed in one mechanical simulation (Briggs et al, 2007), possibly into the characteristic patterns of hummocks and hollows observed in the field (Morris et al, 2013;Pearsall, 1956) and in some coal seams (Broadhurst & Simpson, 1983;Rippon, 1998). Such wrinkles could conceivably generate water channels leading to erosion, drainage and oxidation of a raised peatland under sustained wet conditions.…”
