Phosphorus components and barite in untreated and in carbonate-free sediments...

We determined changes in equatorial Pacific phosphorus (µmol P/g) and barite (BaSO4; wt%) concentrations at high resolution (2 cm) across the Paleocene/Eocene (P/E) boundary in...本研究以2 cm的采样间距对横跨古新世-始新世（Paleocene/Eocene, P/E）界线的赤道太平洋沉积物开展高分辨率分析，测定了其中磷（µmol P/g）与重晶石（barite, BaSO₄；wt%）的浓度变化。
