Earthwatcher's photos with the keyword: recumbent folds

Originally uploaded as a clue for a Guesswhere UK photo. The Strangles beach near Crackington Haven, north Cornwall, looking to the southwest.

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.

A recumbent fold in the Crackington Formation (upper Carboniferous) at The Strangles, near Crackington Haven, north Cornwall. Axial planar cleavage is well-developed. The well-exposed underside of one of the bedding planes displays prominent sole structures.

Detail of part of a recumbent fold in the Crackington Formation (upper Carboniferous) at The Strangles, near Crackington Haven, north Cornwall. Axial planar cleavage is well-developed and is refracted (changes direction) in alternating weaker and stronger (sandier) beds.

Little Barton Strand is a rocky inlet just north of Pencannow Cliff and Crackington Haven, notth Cornwall. The stripy rocks are interbedded grey shales and turbidite sandstones of the Crackinton Formation (upper Carboniferous), which are mostly inverted - turned upside down - by the Variscan earth movements at the end of the Carboniferous. This locality is also where the truncated Cleave valley terminates abruptly. Its waterfall can be seen on the far right plunging over a near vertical lip on to the rocky beach.

A panorama composed from four portrait-style photos joined using Canon's PhotoStitch software. Just north-east of Boscastle, the short, steep-sided Pentargon valley ends abruptly, its waterfall plunging 120 ft over the sheer lip into the Pentargon inlet below. There are a number of these truncated valleys on the north Cornwall coast. Few of them extend far inland and often end with a spectacular, if small, waterfall over a vertical drop to the beach below. The rocks are shales with thin turbidite sandstones - part of the Crackington Formation (upper Carboniferous) - which are deformed into tight horizontal recumbent folds.

A zoomed-in view of the base of the cliff on the north side of Crackington Haven, north Cornwall. Grey shales and thin turbidite sandstones, (pale grey-brown) of the Crackington Formation (upper Carboniferous) have been strongly deformed into isoclinal recumbent folds by the Variscan earth movements at the end of the Carboniferous. For an interpretation and further details, see this photo:

Taken from the spectacular South West Coastal Path, between Boscastle and Crackington Haven. The rocks are shales with thin turbidite sandstones - part of the Crackington Formation (upper Carboniferous) - which are deformed into tight horizontal recumbent folds. The coastal path follows the cliff indentations and gives tremendous views.

Pentargon is a beautiful rocky inlet just north-east of Boscastle, on the coast of north Cornwall. Viewed here from the truncated lip. Here, the short, steep-sided Pentargon valley ends abruptly, its waterfall plunging 120 ft over the sheer lip into the Pentargon inlet below. There are a number of these truncated valleys on the north Cornwall coast. Few of them extend far inland and often end with a spectacular, if small, waterfall over a vertical drop to the beach below.
