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 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
