Carbon dating discovered in 1955, proved very helpful for establishing absolute dating in various archaeological sites.

Potassium-Argon (K40) method extends the range of absolute dating beyond the limit of radio-carbon.

It has been used in Baltic area, North America, South America and Africa.

In North America, Ernst Antevs has made several attempts to relate Pleistocene geological formations in the American Southwest to events that produced varves in the northern parts of North America.

Besides these two a number of other absolute method like thermo luminescence, dendrochronology, Electron Spin Resonance etc.

also proved very helpful for dating various events of the past.

As the damage sites are permanent, a simple count of their number allows an age to be measured.

Second, many of the Pleistocene glacial areas has receded nowadays and affecting the supply of sediments.

Such treatment are used to create etch pits of optical size, each one making a single fission site.
