Cascades of recumbent chevron folds in the turbidite sequence of the Crackington Formation (upper Carboniferous) at Millook Haven, north Cornwall, lit by the late afternoon sun. The northward-dipping (to the left) limbs of the folds are the inverted (upside-down) limbs.

An unusual view of the intensely folded turbidite sequence in the Crackington Formation (upper Carboniferous) at Millook Haven, north Cornwall. The northward-dipping limbs of the folds e.g. the striped sequence in the lower left quadrant are the inverted (upside-down) limbs.

The is an unusual detail view of the rocks at Millook Haven, north Cornwall. The striped rocks are turbidites belonging to the Crackington Formation (upper Carboniferous). Way-up structures in the sandstone bands such as fining-up sequences, small-scale slump structures, ripple marks and grooves, etc, demonstrate that these northward dipping rocks (part of the famous chevron fold sequence) have been inverted and are upside-down.

Originally uploaded for the Guesswhere UK group. This is a view of the upper cliff overlooking The Strangles, near Crackington Haven, north Cornwall. The cliff is comprised of the Crackington Formation: upper Carboniferous turbidites and shales, which have been subjected to intense folding and a near-horizontal axial-planar, slaty cleavage is well developed in the shaly parts of the sequence, as in this location. The cliff has been extensively quarried in the past for slates.

The title says it all really.... Selwicks, Bay, Flamborough, East Yorkshire. Note the capping of brown glacial till ('boulder clay') overlying the Chalk cliffs.

Molk Hole is an intriguing irregularly-shaped inlet at the north end of Selwicks Bay, Flamborough. A fascinating area of Chalk cliffs, sea caves and arches, hollowed out along fault and fracture zones in part of the Howardian Hills-Flamborough Fault Belt. A lovely place to explore at low tide.

Small faults cutting the Chalk at the north end of Selwicks Bay, Flamborough. The Chalk here is disturbed by the Howardian Hills-Flamborough fault belt, although this particular bit is not particularly deformed. I also liked the colours and textures in the lower part of the cliff.
