biogenic silica investigation

A geochemical investigation of Late Holocene lake sediment ... Biogenic silica, stable isotopes (δ13C and δ15N), elemental carbon and nitrogen and compound-specific lipids (n-alkanes and carboxylic acids) were examined in two sediment cores, 28 and 36 cm, collected from Pyramid Lake to shed light on organic Biogenic silica - revolvy Nov 22, 2016· Biogenic silica (bSi), also referred to as opal, biogenic opal, or amorphous opaline silica, forms one of the most widespread biogenic minerals. For example, microscopic particles of silica called phytoliths can be found in grasses and other plants. Silica is an amorphous metal oxide formed by complex inorganic polymerization processes.
