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 ...
Stratigraphy is a key concept to modern archaeological theory and practice. Modern excavation techniques are based on stratigraphic principles. The concept derives from the geological use of the idea that sedimentation takes place according to uniform principles.
She contributed to over 70 publications during her career, including Unlocking the Stratigraphical Record: Advances in Modern Stratigraphy. [4] In 1969, Cox became the first female palaeontologist employed by the Institute of Geological Sciences (IGS), later known as the British Geological Survey (BGS). [5]
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 term "facies" was introduced by the Swiss geologist Amanz Gressly in 1838 and was part of his significant contribution to the foundations of modern stratigraphy, [3] which replaced the earlier notions of Neptunism.
Modern stratigraphic dating has established that the "Mound builders" have spanned an extended period of more than five millennia so that any ethnolinguistic continuity is unlikely. The spread of the Mississippian culture from the late 1st millennium CE most likely involved cultural assimilation, in archaeological terminology called ...
Memorial stone of Amanz Gressly at Verenaschlucht near Solothurn, Switzerland. Amanz Gressly (17 July 1814 – 13 April 1865) was a Swiss geologist and paleontologist.He introduced the use of the term facies in geology, and is considered one of the founders of modern stratigraphy and paleoecology.
His investigations and his subsequent conclusions on these topics have led scholars to consider him one of the founders of modern stratigraphy and geology [13] [14] (Steno, who became a Catholic as an adult, was eventually made a bishop, and was beatified in 1988 by Pope John Paul II. Therefore, he is also called Blessed Nicolas Steno).
