Sopwith Model XII: Denudation of mineral veins
This model shows the influence of surface denudation and faulting on inclined strata, with increased complexity to the situation in Model VII

Sopwith Model VII: Surface denudation of veins
This model shows the influence of surface denudation and faulting on otherwise flat, horizontal strata. The discontinuity between the beds as viewed at the surface can be seen

Sopwith Models: denudation & faulting
Models showing the effect of denudation and faulting on how rock strata appear at the surface. Thomas Sopwith (1803 - 1879)

Sopwith Model II: Coal strata near Newcastle
Unlike the models of generic situations this representation of coal strata was specific to a particular surveyed location in England showing several thin, and mostly hidden, coal seams

Sopwith Model VII: Denudation of mineral veins
This model shows the influence of surface denudation and faulting on otherwise flat, horizontal strata. The discontinuity between the beds as viewed at the surface can be seen

Sopwith Model XII: Mineral vein denudation
This model shows the influence of surface denudation and faulting on inclined strata, with increased complexity to the situation in Model VII

Sopwith Model VIII: Overcutting of strata
This model shows overcut strata: when the layers of rock are inclined at a gentler angle than the eroded slope, the resulting vee pattern points uphill

Sopwith Model X: Denuded basset of strata
This model shows undercut strata: when the layers of rock are inclined at a steeper angle than the eroded slope, the resulting vee pattern points downhill

Sopwith Model IV: Fallacious coal indications
This model depicts the scenario where from the surface an abundance of coal appears to exist, but there is actually very little quantity below

Sopwith Model III: Dislocation of strata
This model represents the side of a valley of denudation, with undisturbed horizontal beds of sedimentary rock when fully assembled

Sopwith Model I: Stratified rocks / denudation
Black lines in this model represent coal seams, between lighter shales and sandstones. When separated the lower section shows a gently inclined valley floor

Sopwith Model II: Coal strata nr Newcastle
Unlike the models of generic situations this representation of coal strata was specific to a particular surveyed location in England showing several thin, and mostly hidden, coal seams

Ordovician Britain
An artists impression of an eroded Ordovician (490 to 443 million years ago) volcano and shore line near Builth Wells, Powys

Gorhams Cave, Gibraltar
A view of Gorhams Cave from the sea. Neanderthal artifacts have been found, dating from the Middle Palaeolithic inside this cave system

Dreikanters, three sided Ventifacts
Two Dreikanters, three sided Ventifacts which are wind-abraded pebbles created by the abrasive process called sandblasting on the side facing the wind

Onion skin boulder
Onion skin is a type of weathering where thin layers are exfoliated by erosion processes producing an onion skin effect

Badlands National Monument - South Dakota - A weird dead area seemingly a propos of nothing at all. Amost a faded negative of Bryce Canyon, pinnacles eroded out of the soft grey soil

The Eddystone Lighthouse, 1879
Engraving of the Eddystone lighthouse built by Smeaton in 1759 and the foundations of the new lighthouse, designed by Sir James Douglass

Proposed Eddystone Lighthouse, 1879
Engraving of the new Eddystone Lighthouse that Sir James Douglass had designed, 1879. The foundations of the old lighthouse had eroded and the replacement was completed in 1882

The Sphinx / Circa 1970
The Sphinx, believed to have been built by the Pharoah Chephren around 2650 BC. Extensive weathering has eroded the monument which is undergoing extensive repair
