Types of absolute dating techniques

Correlation of fossil inclusions is a principle of stratigraphy: that strata may be correlated based on the sequence and uniqueness of their floral and faunal content.SYNONYMS OR RELATED TERMS: chronology CATEGORY: technique DEFINITION: The process by which an archaeologist determines dates for objects, deposits, buildings, etc., in an attempt to situate a given phenomenon in time.Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.

This term refers to the relation of one stratigraphical unit to another, by petrological, osteological, lithographic, cultural, chronological, or palaeontological means.

For example, stratigraphic units may be correlated using palaeontological criteria, methods, and position relative to the glacial-interglacial cycle by examining physical and biological attributes.

Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.

Faunal deposits include remains and fossils of dead animals.

The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.

However, not all fossils or remains contain such elements.

This Buzzle post enlists the differences between the absolute and relative dating methods.

Geological specimens that are unearthed need to be assigned an appropriate age.

Other methods include: coin dating, seriation, and amino-acid racemization.

The methods have varying applications, accuracy, range, and cost.

Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.
