Stratigraphy is the study of layered materials (strata) that were deposited over time. By digging from the top downward, the archaeologist can trace the buildings and objects on a site back through time using techniques of typology (i.e., the study of how types change in time).

How is stratigraphy useful?

Stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale. It provides a basis for historical geology, and its principles and methods have found application in such fields as petroleum geology and archaeology.

Why is stratigraphy important to archaeologists?

Stratigraphic studies of archaeological sites are designed to define objectively and categorize the sediments and soils, the contact units between them, and the amount of time they represent, as well as their relationship to the surrounding sediment history.

How can stratigraphy assist in archaeological and paleontological studies?

Stratigraphy is the result of what geologists and archaeologists refer to as the “process of stratification”, or the process by which layers of soil and debris are laid down on top of one another over time. This works the same way for archaeology, and can be used to determine a sequence of events.

What are the different kinds of stratigraphy?

There are several types of stratigraphy that are described below.Geochronology – Radiometric Stratigraphy. Magnetostratigraphy. Stratigraphic Classification, Terminology and Procedure. Facies Stratigraphy. Quantitative Stratigraphy. Sequence Stratigraphy.More items •Feb 17, 2015

What is the study of rock layers called?

Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata. Stratigraphy deals with all the characteristics of layered rocks; it includes the study of how these rocks relate to time.

Who invented biostratigraphy?

Biostratigraphy developed independently in England and France just after 1800 based on the realization well articulated by William Smith that “the same strata were found always in the same order of superposition and contained the same fossils”.

Who studies rocks?

Geologists Geologists are scientists who study a planets solid features, like soil, rocks, and minerals.
