Faulted Yellow Sands, Colin Glen - a view of a waterfall with a light tone visible to the base and sides, in the rocks. (Location: Northern Ireland: County Antrim: Belfast). Date: circa early 1900s
Sopwith Model XII: Denudation of mineral veinsThis 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 veinsThis 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 II: Coal strata near NewcastleUnlike 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 veinsThis 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 VI: Intersecting mineral veinsThis 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 veinsThis 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 denudationThis 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 denudationThis 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 V: Dislocations of coal strataThis 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 indicationsThis 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 strataThis model represents the side of a valley of denudation, with undisturbed horizontal beds of sedimentary rock when fully assembled
