Archaeological Dating Methods - Archaeological Vacations - Archaeological Volunteering

Aegean Dendrochronology Project Homepage, Professor Peter Ian Kuniholm, director, Cornell University __ A fascinating introduction to this method of dating. "Dendrochronology or tree-ring dating has been available as an archaeometric technique for most of this century. Simply stated, trees in temperate zones grow one ring per calendrical year. For the entire period of a tree's life, a year-by-year record or ring pattern is formed that in some way reflects the climatic conditions in which the tree grew. These patterns can be compared and matched ring for ring with trees growing in the same geographical zone and under similar climatic conditions. Following these tree-ring patterns--the sum of which we refer to as chronologies--from living trees back through time, we can thus compare wood from old or ancient structures to our known chronologies, match the ring patterns (a technique we call cross-dating), and determine precisely the age of the wood used by the ancient builder." - From Cornell University - http://www.arts.cornell.edu/dendro/

We, thus, hope to create a vivid platform for all of you." You will find a lot of good generalized information as well as links to databases and more. - From Association for Tree Ring Research - http://www.tree-ring.org/

A new method of archaeological dating by rehydroxylation __ "Their new 'rehydroxylation dating' method stems utilises the fact that fired clay ceramics start to react chemically with atmospheric moisture as soon as it is removed from the kiln. The ultra-slow recombination of moisture appears to be generic in fired-clay ceramics and obeys a precise power law, which acts as an 'internal clock'."  A full paper online. - From royalsocietypublishing.org - http://rspa.royalsocietypublishing.org/site/misc/rehydroxylation.xhtml

Paleomagnetic and Archaeomagnetic Dating __ "After World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. In the early to mid 1960s, Dr. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating."  A good explanation of the procedures and links to additional resources. - From ucsb.edu - http://archserve.id.ucsb.edu/courses/anth/fagan/anth3/Courseware/Chronology/11_Paleomag_Archaeomag.html    
 
Radiocarbon Dating of the Shroud of Turin __ "Very small samples from the Shroud of Turin have been dated by accelerator mass spectrometry in laboratories at Arizona, Oxford and Zurich.
