Field photographs of various complexly deformed layers. a Large complexly deformed layers with multiple lobes (white arrows), separated by narrow flames. Note the presence of nearly-undeformed parallel-bedding in beds overlying the deformed layers. A small syn-sedimentary fault (black arrow) shows shifting of the parallel beds; b Inclined simple-deformed layers (arrow) with thin flames, in trough cross-stratified sandstone, are overlain by undeformed plane-bedded (P) sandstone; c Large complexly deformed layers, sharply truncated (along white line) against overlying cross-beddings in coarse-grained sandstone; d Multi-lobed complexly deformed layers (arrow) in sandstone developed on nearly undeformed plane-bedded (P) sandstone; e Large complexly deformed layers (arrow) developed on top of undeformed plane-bedded (P) coarse-grained sandstone; f Deformed lobes with flames developed in sandstone foresets. Note the absence of deformations in the overlying foresets within the same cross-bedding sets. Length of the hammer in (a), (b), (e), (f) is 30 cm; length of the scale in (c) is 1 m
