What is The Matrix? How do archaeologists use stratigraphy?
Stratigraphy is recorded by archaeologists during excavations. It helps them understand how, and in what timescale, different objects and remains become buried in the ground.
Archaeologists can create a Harris Matrix diagram of the stratigraphy to visualize the sequence of events, the relative age of items, and the differing spatiotemporal relationships between them. This allows archaeologists to build up a four-dimensional (4D) model of how a site has developed over different timespans.
Such interpretations, based on our understanding of archaeological stratigraphy, often underpin the stories we tell about the sites we excavate.

Archaeological Stratigraphy
Stratigraphy is often just as important to archaeologists as it is to geologists, as it provides a highly reliable basis for ordering events in time (ordinal scale). In this video, I talk about some general stratigraphic principles, borrowed from geology, as well as some more specific to archaeology, including ones that the Bermudan archaeologist, Edward Harris, has advocated. I then demonstrate how Harris matrices work, with emphasis on multilineal sequences, introduce the topic of software that generates Harris matrices, and end with a brief introduction to the Unitary Association Method, which allows us to correlate stratigraphic sequences in different sites or different parts of the same site.

STRATIGRAPHY: Stratigraphic classification, Lithostratigraphy and its Units
STRATIGRAPHY:
Stratigraphic classification, Nomenclature, Lithostratigraphy and its Units
Stratigraphic Elements classification
Stratigraphic is a study of the sequential arrangement of stratified rocks which are stacked one above the other, according to the their age. Is systematically arranges and separates the rock bodies of the earth into units based on their inherent properties and attributes. Hence, stratigraphic classification help to understand the geometry and sequence of the rock bodies .
Any rock sequence can be termed as ‘ conformable’ only if its strata were formed without any ‘time gap’ or deposition interruption. However, in nature, there are long gaps in the formation of rock strata due to erosion or non-depositonal phase. Such a surface of non- deposition is termed as a...

Sequence Stratigraphy | Introduction to Sequence Stratigraphy | Carbonate Sequence Stratigraphy
#SequenceStratigraphy #Carbonate #usmangeo
Sequence stratigraphy is a branch of geology that attempts to subdivide and link sedimentary deposits into unconformity bound units on a variety of scales and explain these stratigraphic units in terms of variations in sediment supply and variations in the rate of change in accommodation space (relative sea level, the combination of eustatic sea level and tectonic subsidence).[1] The essence of the method is mapping of strata based on identification of surfaces which are assumed to represent time lines (e.g. subaerial unconformities, maximum flooding surfaces), and therefore placing stratigraphy in chronostratigraphic framework. Sequence stratigraphy is a useful alternative to a lithostratigraphic approach, which emphasizes similarity of the li...

How to learn stratigraphic units of jehlum group and thier contacts - salt range
This video is about strtigraphic units of Jehlum group and their contacts. Actually in this video a method is shown for learning the five stratigraphic units of jehlum group in sequence according to the period of deposition. Once you learned the five units then their contacts are obvious from that sequence. In this video pictures of the five units of jehlum group and thier sedimentary structures are also present for simple explanation.

Christo Marais van Vuuren presents 'A 'How to Guide': Defining Stratigraphic Units'.
Christo Marais van Vuuren (Team Leader Geological Indexing, Geochronology & Stratigraphy, Geoscience Australia) presents 'A 'How to Guide': Defining Stratigraphic Units' at the September 2022 GSA ACT Division Meeting.
Abstract:
Stratigraphy and stratigraphic units are fundamental parts of geological studies and it is neces-sary in most geological work to have some understanding of the stratigraphy of an area, wheth-er it is for minerals, energy or groundwater work. Despite this the vast majority of stratigraphic units that have been created have never been given formal definitions for a variety of reasons.
In this talk I will explain the importance of defining a formal stratigraphic unit in addition to rele-vant terms such as type sections and reference localities etc. and give an overvi...

Welcome to our channel! In this video, we delve into the fascinating world of stratigraphic units and explore how they help us understand Earth's geological history. Join us as we unravel the mysteries of stratigraphy and discover the secrets hidden within rock layers.
Stratigraphic units are fundamental building blocks in geology, providing a framework for studying and interpreting the Earth's rock record. These units are defined by the vertical sequence and arrangement of rock layers, which offer valuable insights into the history of our planet.
In this educational video, we explore the principles and methods used in stratigraphy. We discuss how the Law of Superposition, which states that younger rocks are typically found above older rocks, helps geologists establish the relative ages of different rock layers. We also examine the concepts of original horizontality, lateral continuity, and cross-cutting relationships, which aid in understanding the relative chronology of events recorded in the rock layers.
We delve into the various types of stratigraphic units, including formations, members, beds, and sequences, each representing a distinct package of rocks with specific characteristics. These units can be correlated across different locations, allowing geologists to create detailed stratigraphic columns and construct a comprehensive picture of the Earth's history.
Furthermore, we investigate the applications of stratigraphic units in various fields of study. Stratigraphy helps identify and interpret fossil assemblages, providing important clues about past environments and the evolution of life on Earth. It is also essential in understanding the distribution of natural resources, such as oil, gas, and minerals, as stratigraphic units can act as reservoirs or traps for these valuable substances.
Join us on this visual journey as we showcase stunning rock formations and geological landscapes from around the world. Through clear explanations and engaging visuals, we aim to deepen your understanding of stratigraphic units and their significance in unraveling Earth's history.

Stratigraphy is recorded by archaeologists during excavations. It helps them understand how, and in what timescale, different objects and remains become buried in the ground.
Archaeologists can create a Harris Matrix diagram of the stratigraphy to visualize the sequence of events, the relative age of items, and the differing spatiotemporal relationships between them. This allows archaeologists to build up a four-dimensional (4D) model of how a site has developed over different timespans.

STRATIGRAPHY:
Stratigraphic classification, Nomenclature, Lithostratigraphy and its Units
Stratigraphic Elements classification
Stratigraphic is a study of the sequential arrangement of stratified rocks which are stacked one above the other, according to the their age. Is systematically arranges and separates the rock bodies of the earth into units based on their inherent properties and attributes. Hence, stratigraphic classification help to understand the geometry and sequence of the rock bodies .
Any rock sequence can be termed as ‘ conformable’ only if its strata were formed without any ‘time gap’ or deposition interruption. However, in nature, there are long gaps in the formation of rock strata due to erosion or non-depositonal phase. Such a surface of non- deposition is termed as an ‘unconformity’ Unconformities may envelope small or large time spans depending on the geological process and could be local or regional in extern
Stratigraphic elements
A rock sequence at any place can be described as a part of earth’ history, either with the help of
1)its physical criteria, must as lithological properties of the rocks ( lithostratigraphic criteria
2)with the help of its position in the geological time span ( geochronological criteria )
3)with the help of the development of life on the earth ( biostratigraphic criteria )
Further, the time units can be as simple time units ( e.g, Eras, period or Epochs ) or as an assemblage of stratigraphic sequence formed in a specific time interval ( chronostratigrsphic¬ units)
Hence, there are three criteria of the main elements of stratigraphy:
Chronostatigraphic lithostratigraphic and biostratigraphic.
The earliest geological studies were not particular about the importance of ‘geological time ‘and great emphasis was laid on the stratigraphic succession and the recognition of the rock systems as the fundamental groupings of strata (lithostatigraphy ) when radioactive dating methods for rocks became available, it was possible to date the exact time of formation of a rock. Thus, the chronostragraphic and geochronologic units were chosen as, the scale formation for standard stratigraphic classification.
1)Lithostratigraphy ;
Lithostratigraphy is a sub – branch of stratigraphy which deals with the study of strata or rock layers. Its thrust areas include geochronology , comparative geology and petrology. It mainly use the principle of superposition
Which states that a sedimentary rock layer in the tectonically undisturbed stratum is younger than the one beneath and older than the one above it.
Lithostratigraphic units : when lithological criteria are solely considered for classification of a rock succession,

brief description of lithostratigraphic units is given below;
i)A group ; it is a broad units and comprises of a thick succession of rock formations covering a regional surface of the earth, e.g.; sausar group . two or more formations together maybe included in a unit to form a group. When different groups can be categorized as a mutually related groups then it is called as a Supergroup.
ii) A formation ; A formation is a fundamental unit in the local classification of the rocks. It is a rock succession deposited during a particular Epoch under identical condition of geological environment. It is recognized on the basis of its typical lithological characteristics and stratigraphic position. Hence, it is a genetic unit and is traceable in the local stratigraphic column. The boundaries of the formation are easily recognized in the field and shown on the map, e.g. Trichinopoly formation and uttature formation
iii)A Member : A member is a distinctive unit within a formation. As these are locally present, their names may not be recognized on a regional or ‘lower mudstone member’ are open used. A member may extend laterally from one formation to another.

STRATIGRAPHY:
Stratigraphic classification, Nomenclature, Lithostratigraphy and its Units
Stratigraphic Elements classification
Stratigraphic is a study of the sequential arrangement of stratified rocks which are stacked one above the other, according to the their age. Is systematically arranges and separates the rock bodies of the earth into units based on their inherent properties and attributes. Hence, stratigraphic classification help to understand the geometry and sequence of the rock bodies .
Any rock sequence can be termed as ‘ conformable’ only if its strata were formed without any ‘time gap’ or deposition interruption. However, in nature, there are long gaps in the formation of rock strata due to erosion or non-depositonal phase. Such a surface of non- deposition is termed as an ‘unconformity’ Unconformities may envelope small or large time spans depending on the geological process and could be local or regional in extern
Stratigraphic elements
A rock sequence at any place can be described as a part of earth’ history, either with the help of
1)its physical criteria, must as lithological properties of the rocks ( lithostratigraphic criteria
2)with the help of its position in the geological time span ( geochronological criteria )
3)with the help of the development of life on the earth ( biostratigraphic criteria )
Further, the time units can be as simple time units ( e.g, Eras, period or Epochs ) or as an assemblage of stratigraphic sequence formed in a specific time interval ( chronostratigrsphic¬ units)
Hence, there are three criteria of the main elements of stratigraphy:
Chronostatigraphic lithostratigraphic and biostratigraphic.
The earliest geological studies were not particular about the importance of ‘geological time ‘and great emphasis was laid on the stratigraphic succession and the recognition of the rock systems as the fundamental groupings of strata (lithostatigraphy ) when radioactive dating methods for rocks became available, it was possible to date the exact time of formation of a rock. Thus, the chronostragraphic and geochronologic units were chosen as, the scale formation for standard stratigraphic classification.
1)Lithostratigraphy ;
Lithostratigraphy is a sub – branch of stratigraphy which deals with the study of strata or rock layers. Its thrust areas include geochronology , comparative geology and petrology. It mainly use the principle of superposition
Which states that a sedimentary rock layer in the tectonically undisturbed stratum is younger than the one beneath and older than the one above it.
Lithostratigraphic units : when lithological criteria are solely considered for classification of a rock succession,

#SequenceStratigraphy #Carbonate #usmangeo
Sequence stratigraphy is a branch of geology that attempts to subdivide and link sedimentary deposits into unconformity bound units on a variety of scales and explain these stratigraphic units in terms of variations in sediment supply and variations in the rate of change in accommodation space (relative sea level, the combination of eustatic sea level and tectonic subsidence).[1] The essence of the method is mapping of strata based on identification of surfaces which are assumed to represent time lines (e.g. subaerial unconformities, maximum flooding surfaces), and therefore placing stratigraphy in chronostratigraphic framework. Sequence stratigraphy is a useful alternative to a lithostratigraphic approach, which emphasizes similarity of the lithology of rock units rather than time significance.
Sequence stratigraphy deals with genetically related sedimentary strata bounded by unconformities.
The "sequence" part of the name refers to cyclic sedimentary deposits. Stratigraphy is the geologic knowledge about the processes by which sedimentary deposits form and how those deposits change through time and space on the Earth's surface.

Christo Marais van Vuuren (Team Leader Geological Indexing, Geochronology & Stratigraphy, Geoscience Australia) presents 'A 'How to Guide': Defining Stratigraphic Units' at the September 2022 GSA ACT Division Meeting.
Abstract:
Stratigraphy and stratigraphic units are fundamental parts of geological studies and it is neces-sary in most geological work to have some understanding of the stratigraphy of an area, wheth-er it is for minerals, energy or groundwater work. Despite this the vast majority of stratigraphic units that have been created have never been given formal definitions for a variety of reasons.
In this talk I will explain the importance of defining a formal stratigraphic unit in addition to rele-vant terms such as type sections and reference localities etc. and give an overview of how you can define a stratigraphic unit. I will also give an overview of the Australian Stratigraphic Units Database – a key dataset for stratigraphy at the national scale here in Australia.
