w:Absolute dating, by using radiation via w:isotopes to analyse w:radioactive decay. This is good to analyse recently fossilised organisms via C-14. For longer periods the sediment itself must be analysed, this would give a date for the original material, like an ignious rock formation that is eroded but not the present sedimentary rock.

w:Optically stimulated luminescence, uses the last time that light from the sun reached the material. This only works for burried material

w:Radiometric dating uses radioactive decay like w:Uranium-thorium dating the time since burial that the w:uranium has decayed to w:thorium.
