ROCKMAGNETIC ANALYSIS OF SEDIMENTARY SEQUENCES FOR PALEO-ENVIRONMENTAL RESEARCH

Rockmagnetic analyses are conducted to examine their utility for paleo-environmental research on the following three sedimentary sequences : (1) samples from the Omma Formation of central Japan; (2) cores drilled off the Noosa Heads, Australia; (3) a core drilled from Honnor Submarine Valley, Antarc...

Description
Summary:Rockmagnetic analyses are conducted to examine their utility for paleo-environmental research on the following three sedimentary sequences : (1) samples from the Omma Formation of central Japan; (2) cores drilled off the Noosa Heads, Australia; (3) a core drilled from Honnor Submarine Valley, Antarctica. The sequences (1) and (2) show clear variation of magnetic properties consistent with the changes of depositional environment which correspond to the change of sedimentary circumstances such as Quaternary glacial-interglacial change. Three drilled cores of sequence (2) show high values in magnetic susceptibility during the time range from 14 to 18ka. The age of the sequence (3) is inferred to be beyond the Holocene, however, a preliminary result of magnetic susceptibility for the core shows no remarkable variation.
