Sopwith Model VI: Intersecting mineral veins
This Model, rather than representing the strata as they would appear at the surface, shows how a seam of coal can be displaced in the subsurface by various modes of faulting

Sopwith Model XI: Vertical intersecting veins
This model, when separated, shows the complex interface between faulted strata of rocks. Thomas Sopwith (1803 - 1879) was an eminent geologist

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 VII: Surface denudation
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 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 V: Dislocations of coal strata
This model shows that while very little coal may appear at ground level, coal seams (subject to faults and dislocations) can be found below the ground

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
