Very Short Period Geomagnetic Excursion 18,000 yr BP

Abstract

AS part of the joint study on the palaeolimnology of Lake Biwa-ko and the Japanese Pleistocene, a core 197.2 m long was taken at a point 65.2 m deep in the central region of the lake. The core, containing about forty thin layers of volcanic ashes, is composed chiefly of gyttja and fine clay and is now being analysed in various ways, for example palaeomagnetically. A continuous series of almost 10,000 oriented specimens (each 2×2×2 cm) was taken along the central axis of the core for palaeomagnetic investigations.
