These flat, sheetlike, Proterozoic intrusions are considered by Grocott et al. (1999b) to have been intruded post tectonically, along regional, pre‐existing, flat‐lying banding, bedding and cleavages, by a mechanism of roof uplift and floor depression. Our model (Hutton et al. 1990; Dempster et al. 1991; Brown et al. 1992), differs markedly with this in previously proposing...
