compressive stress were intensely inverted during the Variscan orogeny. In
contrast, NW-SE-trending basins such as the Widmerpool Gulf and
Gainsborough Trough were only mildly inverted (Fig. 12). The inversion
megasequence is characterized by the accumulation of continental red-beds
and molasse in intermontne troughs. Sediment was largely sourced from the
evolving Variscan mountain front in southern England with some local
drainage networks sourced from inversion structures (Besly 1988; Glover &
Powell 1996).
