The principle of original horizontality states that the deposition of sediments occurs as essentially horizontal beds.
2.
Thus the Principle of Original Horizontality is widely, but not universally, applicable in the study of sedimentology, stratigraphy and structural geology.
3.
"' The Principle of Original Horizontality "'states that layers of sediment are originally deposited horizontally under the action of gravity.
4.
As one of Steno's Laws, the Principle of Original Horizontality served well in the nascent days of sedimentary layers are deposited purely horizontally.
5.
Nicolas Steno ( 1638 1686 ) is credited with the law of superposition, the principle of original horizontality, and the principle of lateral continuity : three defining principles of stratigraphy.
6.
Folding in sediments is analysed with the principle of original horizontality, which states that sediments are deposited at their angle of repose which, for most types of sediment, is essentially horizontal.
7.
Accurate description, mapping, and sampling for laboratory analysis of outcrops made possible all of the geologic sciences and the development of fundamental geologic laws such as the law of superposition, the principle of original horizontality, principle of lateral continuity, and the principle of faunal succession.
