This technique requires an inexpensive chemical analysis procedure.

The effective time range for OCR dating has not yet been male sex spores of flowering plants.

When these events are well dated, geochronology could be considered a reliable calibrated relative dating technique.

The rate at which these changes occur depends on the local environment.

Pollen particles are usually nearly invisible, except in large concentrations, due to their extremely small size.

They can survive for hundreds of thousands of years in silty, anaerobic soils, such as mud sediments at the bottom of a lake.

Specifically, light causes electrons of the mineral atoms to be progressively dislodged. So far, the OSL technique has been used to date silty or sandy water deposited sediments that are 1/2 million years old or experimental dating technique based on the fact that organic carbon in soil humus and charcoal progressively convert to oxidizable carbon over time.

The ratios of these two forms of carbon vary directly with the age of the material.

based on the fact that amino acids progressively change to mirror image forms following the death of an organism--i.e., from L-amino acid to D-amino acid forms.
