Phytolith dating websites

Although the term “phytolith” has been used for various types of mineral depositions, siliceous and calcareous particles often reveal substantial differences in their structure and taxonomic attributes.Therefore, it has been suggested that the term “phytolith” be used in a more restrictive sense to refer only to silicified incrustations.Numerous other terms have also been used for silica bodies found in plants, such as “opal phytolith”, “plant opal” and “opaline silica”.

As an important long-term terrestrial carbon sequestration mechanism, biogeochemical sequestration of carbon within phytoliths may play a significant role in the global carbon cycle and climate change.

The aim of this study is to explore the potential of carbon bio-sequestration within phytoliths produced by wetland plants.

The results show that the occluded carbon content of phytoliths in wetland plants ranges from 0.49% to 3.97%, with a CV (coefficient of variation) value of 810%.

The data also indicate that the phytolith-occluded carbon (Phyt OC) content of biomass for wetland plants depends not only on the phytolith content of biomass, but also the efficiency of carbon occlusion within phytoliths during plant growth in herb-dominated fens.

The fluxes of carbon bio-sequestration within phytoliths of herb-dominated fen plants range from 0.003 to 0.077 t CO may be sequestrated in the phytoliths of world wetland plants.

The data indicate that the management of wetland ecosystems (e.g.

Phytoliths are inorganic amorphous oxides (Si O2) formed by the process of polymerization following uptake of monosilicic acid (H4Si O4) from the soil.

Phytoliths are known to boost the growth and development of plants particularly during environmental onslaughts.


  1. Studies of the stability and kinetics of the 325 °C thermoluminescence peak in quartz are described which show the occurrence of thermal quenching, the decrease in luminescence efficiency with rise in temperature.
