    The extraction of biogenic silica from sediment dissolves all forms silica in the sample. The silica components in sediment can be separated between diatoms, sponge spicules, and silicate minerals (Conley et al., 1993). Distinguishing the source of biogenic silica is possible because of the different dissolution rates of the silica components.
