A sequence of layered rocks; often used to describe a particular rock formation associated with a specific area.
The systematic study of layers of sediments, usually to determine the sequence in which past human activities took place.
The sequence or order of rock or soil layers in a geologic formation.
is a branch of geology, that studies and determines the chronological order of Earth crust rocks; it is the basis of any geological investigations.
The study of sequences of rock and their history. Commonly applied to sedimentary rocks, but igneous and metamorphic sequences are studied as well. The concept of stratigraphy includes some of the most important tenets in geology: that sedimentary strata were originally deposited horizontally, that older beds underlie younger beds, and that older rocks are cross-cut by younger ones.
The study of the layering of rocks and soils to determine how they were laid down, what they are made of and how old they are. This study is vitally important in geology to determine how old a rock structure is, and how it was formed as well as providing information about any fossils found in the rock layers.
the study of vertical sequences of rock layers.
either the arrangement of strata in rocks or a sub-discipline of geology that studies the origin, sequence, spacing, composition and spatial distribution of rocks and sedimentary deposits.
The study, definition, and description of major and minor natural divisions of rocks, particularly the study of their form, arrangement, geographic distribution, chronologic succession, classification, correlation, and mutual relationships of rock strata.
Study of rock layers, (particularly sedimentary rocks:), how they were formed, and mapping of their geometry (areal distribution and thickness).
(stra·TI·graphy). The study of the arrangement of rock and/or soil layers together with the study of their origin, the order of their deposition, and their functional and chronological relationships to one another.
the study of rock strata, especially the distribution, deposition, and age of sedimentary rocks
The study of various deposits, built up over time, which form delineated layers (such as ash, charcoal or crushed shell) in the earth walls of a pit.
The study of stratified sedimentary rock sequences.
the study of the sequence and correlation of rock strata in order to interpret the geological history on local and global scales.
a branch of geology concerned with form, arrangement, geographic distribution, chronological succession, classification, correlation and mutual relationships of rock strata, especially sedimentary
The soil levels and strata at a site and how these are associated with each other and the cultural aspects of the site (artifacts and features, etc.).
the study of sedimentary layers in the ground, where individual layers represent a specific episode of time and the properties of those layers reflect the conditions under which they were formed.
The study and interpretation of layers in archaeological deposits.
Features of geology dealing with the origin, composition, distribution, and succession of geologic strata (layers).
the study of the layers of earth laid down in time by man or nature; one layer is called a stratum; more than one is called strata (this is one of the two main principles of archaeology)
The study and interpretation of layered deposits. Stratigraphic information can be used to establish the relative ages of different deposits and to determine when and how features and structures filled with sediment after they were abandoned.
Stratigraphy refers to the interpretion of the layers in archaeological deposits. The artifacts found on top are usually the youngest (more recent) while those on the bottom are the oldest. If the stratigraphy gets mixed up, for example, if someone digs a hole down into it then interpretation is much more difficult and sometimes impossible. Artifacts are no longer in context. By examining and analyzing the layers and the artifacts in them, archaeologists can learn how past people lived and what kinds of things they did.
The study of layered sedimentary or metamorphic rocks and how they related to each other, particularly their ages.
the study of the relative positions of deposits, and the sequence of events associated with them.
A branch of geology dealing with the classification, nomenclature, correlation, and interpretation of stratified rocks.
The study of a series of layers of archaeological deposits. The assumption is usually made that the vertical section can be considered a slice through time demonstrated by various horizontal layers. The deepest of these layers in a simple stratigraphic section would normally be the earliest. It is often possible to date these horizontal layers by artefact content.
layers of sediment deposited over a period of time.
a geological discipline involved with mapping the distribution of rock beds
The branch of geology concerned with the formation, composition, ordering in time, and arrangement in space of sedimentary rocks.
the layering of deposits in archaeological sites. Cultural remains and natural sediments become buried over time, forming strata.
(a) The science of rock strata. It is concerned not only with the original succession and age relations of rock strata but also with their form, distribution, lithologic composition, fossil content, geophysical and geochemical properties -- indeed, with all characters and attributes of rocks as strata; and their interpretation in terms of environment or mode of origin, and geologic history. All classes of rocks, consolidated or unconsolidated, fall within the general scope of stratigraphy. Some nonstratiform rock bodies are considered because of their association with or close relation to rock strata. (b) The arrangement of strata, esp. as to geographic position and chronologic order of sequence. (c) The sum of the characteristics studied in stratigraphy; the part of the geology of an area or district pertaining to the character of its stratified rocks. (d) A term sometimes used to signify the study of historical geology.
Stratigraphy - A discipline of geology dealing primarily with the chronological order and geographic distribution of rock layers (strata).
The study of sedimentary rock units, including their geographic extent, age, classification, characteristics and formation.
The science of the description, correlation, and classification of strata in sedimentary rocks, including the interpretation of the depositional environments of those strata.
Description of major and minor divisions of surface and subsurface geologic formations.
the study of the layers of deposits at archaeological sites. The Study of the sequence of data and their dates
( stratigraphie) the composition and arrangement of geographic strata or layers of earth in a particular area.
The succession or superimposition of rock strata.
A study of the formation, composition, sequence and correlation of stratified sediment, soils and rocks. Stratigraphy is the principal means by which the context of archaeological deposits is evaluated, chronologies are constructed and events sequenced.
The arrangement of geologic materials, and the depositional environments they represent, in both time and space.
the study of the succession of rock layers that were deposited on the earth's surface.
A branch of geology, studying rock and sediment layers.
The study of layers, sequentially deposited over time. This is very helpful for land archaeology. Under water it can also be useful, but it's more complicated and often confusing because of current and sea movement. This is explained in: Archaeology Underwater – the NAS Guide to Principles and Practice (1992) and Keith Branigan's Archaeology Explained (Duckworth 1973, 1988).
Strictly, the description of bedded rock sequences; used loosely, the sequence of bedded rocks in a particular area.
The study of the sequence and characteristics of sedimentary rocks (including the fossil record) which allows the history of the Earth and of life on Earth to be investigated.
The study of rock layers, or strata. The way in which successive layers of rock are laid down over time, especially in sedimentary rocks, provides us with a geological timeline of the Earth's history.
The layers consisting of structural remains, soil and artifacts that make up an archaeological feature or site.
the study of rock strata and the relationships between them.

scientific classification of rock or sediment strata according to attributes of the strata: Lithostratigraphy = Organization of strata into units based on their lithological character. Biostratigraphy = Organization of strata into units based on their fossil content. Chronostratigraphy = Organization of strata into units based on their age (time). Morphostratigraphy = Organization of strata into units based on their surface morphology (landforms).

the successive deposition of superimposed layers of either natural or cultural material
a description of the rock formations in sequence from top to bottom in a sedimentary basin.
Stratigraphy is a method of dating fossils by observing how deeply a fossil is buried. Sedimentary rock layers (strata) are formed episodically as earth is deposited horizontally over time. Newer layers are formed on top of older layers, pressurizing them into rocks. Paleontologists can estimate the amount of time that has passed since the stratum containing the fossil was formed. Generally, deeper rocks and fossils are older than fossils found above them.
The study of stratified rocks especially their sequence in time., the character of the rocks and the correlation of beds in different locations
Refers to the interpretation of the layers in archaeological deposits. By examining and analyzing the layers (strata) and the artifacts in them, archaeologists can learn how past people lived and what kinds of things they did. Usually, the artifacts found on top are the youngest (most recent), while those on the bottom are the oldest. If the stratigraphy gets mixed up (for example, if someone digs a hole down into it) then interpretation becomes much more difficult, and sometimes impossible. If this happens, artifacts are no longer in context.
The layering of rock or ice strata, from which information on succession, age relations, and origin can be deduced.
The study of sedimentary rock layers. Stratigraphy includes deposition, age, distribution, and other characteristics.
the study of the layers of sediment in an archeological site. Stratigraphy provides relative dating information: objects found in strata (or layers) overlaying other objects must have been deposited later.
the branch of geology that deals with the order and position of strata. [AHDOS
Stratigraphy, a branch of geology, is basically the study of rock layers and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy includes two related subfields: lithologic or lithostratigraphy and biologic stratigraphy or biostratigraphy.
