Biogenic silica sedimentation in the central equatorial Pacific during the Cenozoic
A new technique for determining the amount of opal in deep-sea sediments of any age is described. Using a normative calculation, a portion of the analytical silica concentration of sediments is subtracted as non-biogenic in proportion to the concentration of aluminum in the sample. The ratio of SiO₂...
