Particle-size distributions of Eocene-Oligocene sediment from ODP Site 742, Prydz Bay

This dataset contains measurements of terrigenous particle-size distributions on Eocene-Oligocene sediment from Ocean Drilling Program Site 742 in Prydz Bay. Carbonate and organic matter were removed through addition of 10mL aliquots of 30% H2O2, 2mL aliquots of 10% HCl to ~50-100mL suspension on a...

Description
Summary:This dataset contains measurements of terrigenous particle-size distributions on Eocene-Oligocene sediment from Ocean Drilling Program Site 742 in Prydz Bay. Carbonate and organic matter were removed through addition of 10mL aliquots of 30% H2O2, 2mL aliquots of 10% HCl to ~50-100mL suspension on a hot plate. Dispersion was through heating with sodium pyrophosphate. Samples were measured on a Malvern Mastersizer 2000 with a Hydro 2000MU (A) accessory, using a Refractive index of 1.544 (Quartz) and an absorption coefficient of 0.9. Results are in (vol. %) per size class, with diameter range equivalent to the diameter of spheres with the same volume as measured particles.
