Methods of absolute hookup in archaeology


Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar datingas use of the word "absolute" implies an unwarranted certainty of accuracy.

In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.

Dating Methods

Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geologythe primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on earth.

; second main absolute dating...

Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes. Particular isotopes are suitable for different applications due to the type of atoms present in the mineral or other material and its approximate age. For example, techniques based on isotopes with half lives in the thousands of years, such as Carbon, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.

One of the most widely used and well-known absolute dating techniques is carbon or radiocarbon dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay. Carbon moves up the food chain as animals eat plants and as predators eat other animals. With death, the uptake of carbon stops. It takes 5, years for half the carbon to change to nitrogen; this is the half-life of carbon After another 5, years only one-quarter of the original carbon will remain.

After yet another 5, years only one-eighth will be left. By measuring the carbon in organic materialscientists can determine the date of death of the organic matter in an artifact or ecofact. The relatively short half-life of carbon, 5, years, makes the reliable "Methods of absolute hookup in archaeology" up to about 50, years.

The technique often cannot pinpoint the date of an archeological site better than historic records, but is highly effective for precise dates when calibrated with other dating techniques such as tree-ring dating. An additional problem with carbon dates from archeological sites is known as the "old wood" problem. It is possible, particularly in dry, desert climates, for organic materials such as from dead trees to remain in their natural state for hundreds of years before people use them as firewood or building materials, after which they become part of the archaeological record.

Thus dating that particular tree does not necessarily indicate when the fire burned or the structure was built. For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating.

The development of accelerator mass spectrometry AMS dating, which allows a date to be obtained from a very small sample, has been very useful in this regard. Other radiometric dating techniques are available for earlier periods. One of the most widely used is potassium—argon dating K—Ar dating. Potassium is a radioactive isotope of potassium that decays into argon The half-life of potassium is 1.

Potassium is common in rocks and minerals, allowing many samples of geochronological or archeological interest to be dated. Argona noble gas, is not commonly incorporated into such samples except when produced in situ through radioactive decay.

The date measured reveals the last time Methods of absolute hookup in archaeology the object was heated past the closure temperature at which the trapped argon can escape the lattice.

K—Ar dating was used to calibrate the geomagnetic polarity time scale. Thermoluminescence testing also dates items to the last time they were heated. This technique is based on the principle that all objects absorb radiation from the environment.

This process frees electrons within minerals that remain caught within the item. Heating an item to degrees Celsius or higher releases the trapped electronsproducing light. This light can be measured to determine the last time the item was heated. Radiation levels do not remain constant over time. Fluctuating levels can skew results — for example, if an item went through several high radiation eras, thermoluminescence will return an older date for the item.

Many factors can spoil the sample before testing as well, exposing the sample to heat or direct light may cause some of the electrons to dissipate, causing the item to date younger. It cannot be used to accurately date a site on its own. However, it can be used to confirm the antiquity of an item. Optically stimulated luminescence OSL dating constrains the time at which sediment was last exposed to light.

During sediment transport, exposure to sunlight 'zeros' Methods of absolute hookup in archaeology luminescence signal. Upon burial, the sediment accumulates a luminescence signal as natural ambient radiation gradually ionises the mineral grains. Careful sampling under dark conditions allows the sediment to be exposed to artificial light in the laboratory which releases the OSL signal. The amount of luminescence released is used to calculate the equivalent dose De that the sediment has acquired since deposition, which can be used in combination with the dose rate Dr to calculate the age.

Dendrochronology or tree-ring dating is the scientific method of dating based on the analysis of patterns of tree ringsalso known as growth rings.

Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year.

It is a relative dating...

Dendrochronology has three main areas of application: In Methods of absolute hookup in archaeology areas of the world, it is possible to date wood back a few thousand years, or even many thousands.

Currently, the maximum for fully anchored chronologies is a little over 11, years from present. Amino acid dating is a dating technique [5] [6] [7] [8] [9] used to estimate the age of a specimen in paleobiologyarchaeologyforensic sciencetaphonomysedimentary geology and other fields. This technique relates changes in amino acid molecules to the time elapsed since they were formed. All biological tissues contain amino acids. All amino acids except glycine the simplest one are optically activehaving an asymmetric carbon atom.

This means that the amino acid can have two different configurations, "D" or "L" which are mirror images of each other. With a few important exceptions, living organisms keep all their amino acids in the "L" configuration. When an organism dies, control over the configuration of the amino acids ceases, and the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization.

Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. Methods of absolute hookup in archaeology Wikipedia, the free encyclopedia.
