Phosphorus partition and acumulation rates in sediments of ODP Legs 130 and 138, supplement to: Filippelli, Gabriel M; Delaney, Margaret Lois (1996): Phosphorus geochemistry of Equatorial Pacific sediments. Geochimica et Cosmochimica Acta, 60(9), 1479-1495

Gabriel M Filippelli & Margaret Lois Delaney
Understanding phosphorus (P) geochemistry and burial in oceanic sediments is important because of the role of P for modulating oceanic productivity on long timescales. We investigated P geochemistry in seven equatorial Pacific sites over the last 53 Ma, using a sequential extraction technique to elucidate sedimentary P composition and P diagenesis within the sediments. The dominant P-bearing component in these sediments is authigenic P (61-86% of total P), followed in order of relative dominance by...
