Archaeological stratigraphy at the Iron Age site of Goosehill Camp on Bow Hill, West Sussex in Southern England. Neat stratification in Athens (Ceramicus Cemetery). Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles.
The principles of lithostratigraphy were first established by the Danish naturalist, Nicolas Steno, in his 1669 Dissertationis prodromus. [1] A lithostratigraphic unit conforms to the law of superposition, which in its modern form states that in any succession of strata, not disturbed or overturned since deposition, younger rocks lies above older rocks.

The Permian through Jurassic stratigraphy of the Colorado Plateau area of southeastern Utah is a great example of Original Horizontality and the Law of Superposition, two important ideas used in relative dating.
Stratigraphy is a branch of geology concerned with the study of rock layers and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks . Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy ...
The oldest known figurative art from Sub-Saharan Africa are seven stone plaquettes painted with figures of animals found at the Apollo 11 Cave complex in Namibia, and dated to between 27,500 and 22,500 years ago. [41] [42] There is a substantial amount of rock art attributable to the Bushmen (San) found throughout Southern Africa. Much of this ...
The initial objective at Gatecliff Rockshelter, Nevada was establishing and dating a stratigraphic sequence that could be applied regionally in the Great Basin area; this would require a vertical excavation strategy. During the early excavations, the deposits were troweled and screened with a 1/8 inch mesh screen. [4]
The list is full of examples of this art style and movement that were created by artists from all around the world. So, check them out; maybe it will convince you to become a surrealism enthusiast ...
An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology , but all were deposited in the same vast erg . [ 3 ]
