The principle of original horizontality states that layers of
folded strata.[2]
As one of Steno's Laws, the principle of original horizontality served well in the nascent days of
sand dunes
.
Similarly, sediments may drape over a pre-existing inclined surface: these sediments are usually deposited conformably to the pre-existing surface. Also, sedimentary beds may pinch out along strike, implying that slight angles existed during their deposition. Thus the principle of original horizontality is widely, but not universally, applicable in the study of sedimentology, stratigraphy, and structural geology.
