Magnetic susceptibility of lake sediments

Abstract

Initial magnetic susceptibility in Flandrian sediments from Lough Neagh, N. Ireland, is shown to be a function of the detrital titanomagnetite of the sediment. Parallel susceptibility changes are synchronous from core to core and thus potentially valuable for core correlation especially in view of the rapid nondestructive techniques developed for measurement. Changing susceptibility in the lake sediments studied appears to be positively correlated with variations in the amount of inwashed inorganic allochthonous material present in the cores.
