“…Because of variations in the water content of near-surface sediments, specific-susceptibility measurements are the only ones which can be used to record variations right up to the mud-water interface. Radhakrishnamurthy et al 1968;Lal & Somayajulu 1975). Ipea core 6), the single-sample measurements were carried out on samples too small to give repeatable susceptibility measurements.…”

“…As calcium carbonate has a diamagnetic susceptibility similar to that of water (Collinson, 1983), negative susceptibility values were taken as an indication that the cored material contained very little other than water and car bonate. Conversely, cores giving positive susceptibility readings were assumed to indicate the presence of minute amounts of ironbearing minerals (e.g., Radhakrishnamurty et al, 1972;Ellwood, 1980).…”

“…The apparatus used in the present study is almost identical to the one developed by Radhakrishnamurty et al (1968), but for the transistorised electronic unit and double coils of different sizes. Details of the instrument and experimental procedures have been previously described by Likhite (1965), Likhite and Radhakrishnamurty (1965), and Radhakrishnamurty et al (1968).…”

“…It appears that the maximum of type 2 bump can act as a stratigraphic marker since type 2 cores are the most common ones and are widely distributed. over the Radhakrishnamurty et al (1968) had shown that the variation ofmagnetic susceptibility (termed susceptibility henceforth) of marine sediments with depth can be con-venientIy studied by a simple and rapid logging technique. With this technique it was possible to show that: (i) the susceptibility variation in a long sediment core of any diameter could be determined (using suitable double coils) with a high sensitivity and, (ii) for magnetic reversal studies cores showing large variations of susceptibility along the entire length are unsuitable; also such cores generally do not conform to the Qn criterion (Amin et a/1972).…”
