Abstract
Samples of 257 argillaceous sediments are generally enriched in SiO2 and impoverished in MnO, compared with typical pelagic sediments. SiO2 is negatively correlated with other oxides. Statistical treatment of data shows that pure silica varies inversely with TiO2 and Al2O3. The silica was derived mainly from planktonic siliceous organisms such as diatoms and radiolarians.-from Authors
