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. Thomas Sopwith (1803 - 1879) was an eminent geologist and civil engineer who pioneered methods of representing geological features. This set of wooden models were designed to represent geological situations with faults, folds, inclines and strata that were particularly relevant to the mining industry.
