- Abstract
The article provides information on biogenic silica. It explains why the biogenic silica is considered as a neglected component of the coupled global continental biogeochemical cycles of carbon and silicon. It is stated that the geochemical cycles of carbon and silicon are matched by the drawdown of atmospheric carbon dioxide through chemical weathering of minerals in continental rocks. Soluble products of weathering such as cations, alkalinity, and silinic acid are discussed and marine ecosystems are tackled to add knowledge. Topics of biogeochemistry, lake sediments, diatoms, and phytoliths are also covered by the article.
