Abstract:
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.
