    Wet-bulk density and mean silt diameter gradients for density anomaly intervals in ODP Hole 105-645E (Table 1) (1989)

    Description: Terrigenous sediments between 800 and 1147 mbsf at Site 645 in Baffin Bay display intervals tens of centimeters thick, in which wet-bulk density either rapidly increases or decreases. Grain-size analyses were performed on multiple samples from these anomalous intervals to determine if the density change is a response to textural variation. Analyses indicate a weak correspondence at best between grain size and density variation. The correlation is not sufficiently strong to use the density records as direct grain-size indicators.

    ARM and susceptibility record ans grain size distribution of ODP Hole 105-645C (Table 1) (1989)
    PANGAEA
    In:  Supplement to: Hall, Frank R; Busch, William H; King, John W (1989): The relationship between variations in rock-magnetic properties and grain size of sediments from ODP Hole 645C. In: Srivastava, SP; Arthur, M; Clement, B; et al.

    Description: The potential use of anhysteretic remanence/magnetic susceptibility (ARM/X) to indicate the relative grain-size variations of marine sediments is examined. Samples from Ocean Drilling Program (ODP) Hole 645C were measured for low-field magnetic susceptibility at two frequencies (0.47 and 4.7 kHz), given an anhysteretic remanence using a peak alternating magnetic (AC) field of 0.05 mT, and separated into the percentage sand, silt, and clay fractions. Results show little frequency dependence of low-field magnetic susceptibility and a direct relationship betweem ARM/X and clay concentration.
