Dating datexp

Thus, Sir Arthur Evans was able to establish an accurate absolute chronology for the ancient civilizations of Crete and Greece through the use of Egyptian trade objects that appeared in his excavations—a technique known as cross-dating.In dendrochronology, the age of wood can be determined through the counting of the number of annual ringsannual rings,the growth layers of wood that are produced each year in the stems and roots of trees and shrubs.The method begins with the careful drawing and description of strata (the geological or archaeological profile).The profile from one location is then compared with profiles from surrounding sites.The seriation of stratified deposits permits archaeologists to assess the relative age of particular styles.

There are two basic types of dating methods, relative and absolute.Through the investigation of many different stratigraphic contexts, a master sequence of fossil and floral assemblages may be devised for a region.Absolute dating can be achieved through the use of historical records and through the analysis of biological and geological patterns resulting from annual climatic variations, such as tree rings (dendrochronology) and varve analysis.Other techniques are occasionally useful, for example, historical or iconographic references to datable astronomical events such as solar eclipses (archaeoastronomy).When archaeologists have access to the historical records of civilizations that had calendars and counted and recorded the passage of years, the actual age of the archaeological material may be ascertained—provided there is some basis for correlating our modern calendar with the ancient calendar.
