Little Haven - Fox Hole Anticline
Structural geology of Little Haven and The Settlands
The cliffs from Little Haven to Broad Haven (and northward) display a spectacular range of geological structures, folding, faulting and thrusting, mainly in the Lower Coal Measures. The relatively weak mudstone and shale-dominated sequences show much incompetent deformation: tight, thrusted and overturned folds, in contrast to the thicker, stronger, sandstones which have formed relatively open and concentric folds.
This is a view of the Fox Hole anticline taken from beach level. The style of folding is open and concentric, largely due to the competent (strong) nature of the sandstone of which it is comprised. A thin coal in the core of the anticline has largely been extracted by mining.
The sandstone displays a number of sedimentary features, including cross-bedding and channel erosion, formed by deposition in a high-energy delta distributary channel setting. Restoring the anticline to its 'unfolded' condition, these sedimentary structures then indicate a general current flow direction from south-west to north-east.
Folding, faulting and thrusting make determination of the exact stratigraphic correlation of the Fox Hole sandstone difficult, but it is reasonably clear that this is the lowest stratigraphic unit in the Little Haven area and is well down in the Lower Coal Measures sequence.
