Methods for dating of archaeological objects

Dating - a system of dating archaeological remains and strata in relation to each other.

Processes - human-caused or natural processes by which an archaeological site is modified during or after occupation and abandonment.

- accelerator mass spectrometry is an absolute dating technique that measures the amount of carbon-14 in an organic object and provides a rough indication of its age.

In argon-argon dating, the thermoluminescence clock also begins with the last time that a rock was heated to a high temperature.

Dating works well for some archaeological finds, but it has limitations: it can be used to date only organic materials less than about 60,000 years old.

How Does Radiocarbon Dating Work? - Instant Egghead #28

How do scientists determine the age of fossils that have been under the surface of the earth for thousands of years? Scientific ...

Simulate an archaeological survey to recognize and use basic archaeological procedures, analyze survey data, and make inferences about human behavior.

Survey - the process of searching for archaeological remains by physically examining the landscape, usually on foot.

Radiocarbon (c14) dating is the most widely used method to date objects made of organic matter.

Dates are determined by a variety of processes, including chemical analyses (as in radiocarbon dating and thermoluminescence), data correlation (as in dendrochronology), and a variety of other tests.

Excavation of a seaside cave in south africa revealed two objects that were clearly manmadepieces of ocher stone etched with a crisscross pattern.

By using methods of typing or by assigning a sequence based on the law of superposition, archaeologists organize layers or objects in order from "oldest" to "most recent.

- the study of the layers (strata) of sediments, soils, and material culture at an archaeological site (also used in geology for the study of geological layers).

While some objects are legally obtained, many are purchased from looters who destroy archaeological sites in their attempts to find artifacts.

- the name given to a european stone-tool industry characterized by flakes struck from prepared cores, dating from about 150,000 until 35,000 years ago.

(tl) - a radiometric dating technique in which the amount of light energy released when heating a sample of pottery or sediment is measured as an indicator of the time since it was last heated to a critical temperature.

Relative and Absolute Dating Methods

Archaeologist Steve Davis of the University of North Carolina at Chapel Hill explains the methods archeologists use to determine ...

- a method of gathering data, often associated with surface surveys, in which archaeological remains are systematically identified and plotted on a map.

Archaeology - a discipline within archaeology concerned with supplementing written history with archaeological research to create a more complete account of the past.

Cut out and identify illustrations of artifacts, and paste them into layers of soil to illustrate the stratigraphy found on an archaeological site.

Are a variety of techniques that can be used to find out how old an artifact or an archaeological site is.

Dates generated by radiocarbon dating have to be calibrated using dates derived from other absolute dating methods, such as dendrochronology and ice cores.

Harris as a way to simplify the representation of the stratigraphy at an archaeological site.

The organic remains were too old for carbon-14 dating, so the team turned to another method.

However, in the same rock layer as the ochers were pieces of burnt stone, which were likely the same age as the ochers and ideal for thermoluminescence dating.

Goods - objects placed within human burials to equip a person for the afterlife or to identify the deceased.

- the digging up and recording of archaeological sites, including uncovering and recording the provenience, context, and three-dimensional location of archaeological finds.

Organic remains decay and are not preserved as well as inorganic remains in the archaeological record.

- the three-dimensional context (including geographical location) of an archaeological find, giving information about its function and date.

Dirt - the excavated, discarded material (sediment, dirt) from a site that has generally been sifted for artifacts and is presumed to be of no further archaeological significance.

That was once part of a living objectsuch as charcoal, wood, bone, pollen or the coprolites found in oregoncan be sent to a lab where scientists measure how much carbon-14 is left.

- a specific point in space; a discrete excavated unit or archaeological context (plural = loci).

In academic, historical, and archaeological circles, this term is now generally replaced by before common era (b.

Sensing - non-intrusive survey methods used to find archaeological sites; these may include aerial reconnaissance and geophysical techniques such as magnetometry, radar, resistivity, and conductivity.

Of superposition - a physical "law" asserting that deeper layers of sediment or archaeological strata will naturally be older than the layers above them (in the absence of unusual, disruptive, activity, such as earthquakes).

- annual clay deposits made by retreating and melting glaciers, used to measure recent geological events; may be used for relative dating.

This is just a sample of the many physical and chemical dating methods that archaeologists have used to date archaeological sites.
