Correlation with them has helped geologists date many New Zealand rocks, including those containing dinosaurs.Bring relative dating principles to life with the activity Rock layers and relative dating.Throughout the history of life, different organisms have appeared, flourished and become extinct.Many of these organisms have left their remains as fossils in sedimentary rocks.One can obtain results from charcoal where rings can still be visible.Bannister and Smiley (199) stipulate four basic requirements for dendrochronology research: there must be trees that produce clearly defined annual rings as a result of a definite growing season tree growth must be principally dependent upon one controlling factor there must have been an indigenous prehistoric population that made extensive use of wood the wood must e well enough preserved so that it still retains tis cellular structure Glacial Varve sequences Melt water basins of retreating glaciers create annual deposits of thin clay laminae and go back to 20,000 years in some cases.
Correlation can involve matching an undated rock with a dated one at another location.lexicostatic dating and glottochronology This is a technique used to estimate the age of languages and the dates of divergence between two languages. Dating techniques are procedures used by scientists to determine the age of an object or a series of events.Seriation Using chronological sequences of styles, types, or assemblages of types (cultures) can be useful to date a site, but existing sequences have to already be established. The same idea can be applied to lithics, fish hooks, jewelry, etc. Middens and garbage Analysis of the rates of refuse accumulation can provide good information on how long a site is occupied and sometimes when.
