Principle of Original Horizontality Sedimentary strata are deposited in layers that are horizontal or nearly horizontal, parallel to or nearly parallel to the Earth's surface.Thus, we can deduce that the mudstone and shale are older than the rhyolite dike.But, since the rhyolite dike does not cut across the shale, we know the shale is younger than the rhyolite dike.Principle of Uniformitarianism The principle of Uniformitarianism was postulated by James Hutton (1726-1797) who examined rocks in Scotland and noted that features like mudcracks, ripple marks, graded bedding, etc.where the same features that could be seen forming in modern environments.
