  4. The fluorine method is most suitable for the relative dating of bones in gravelly or sandy alluvial deposits in temperate regions.
  5. Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet.

Thus there is co-relation between the rings of one tree to that of another. Simply assuming that an artefact is older because it was found at a lower depth in the record is only subjective science. These tracks disappear when the glass is heated above a critical temperature and fresh tracks formed in course of time.

Samples should be sundried before pacing in aluminium thin foils and placed in a glass jar or secured safely in thick polythene covers. Seriation is thought to be the first application of statistics in archaeology. Therefore sampling should be done with such material only. Samples which are in contact or near the roots of any plants or trees should not be collected because these roots may implant fresh carbon into the specimens. The changing styles of pottery, glass, stoneware, free and metal objects provide archaeology analysts with known progressive sequences.

This method includes carbon dating and thermoluminescence. Another difficulty that has to be taken into serious consideration is the possibility of uneven distribution of radio carbon in organic matter. Absolute dating methods, by using absolute referent criteria, lead mainly include the radiometric dating methods.

These sheets require data on environment and stratigraphy of the sample, and archaeological estimates of its dating. Thermoluminescence Thermoluminescence uses the phenomenon of ionizing radiations that naturally occur in the atmosphere. See the main article on Radiocarbon Dating for additional information.

Douglass believed that solar flares affected climate, and hence the amount of growth a tree might gain in a given year.
