Palaeomagnetic investigations of Lago Grande di Monticchio, southern Italy
Two long sediment cores were collected from Lago Grande di Monticchio in 1990. Whilst not yet firmly dated, it is generally agreed that this record spans the last 250,000 years. An initial time scale has been calculated for the record by using susceptibility as a proxy climate indicator. The depth to time transform used was confirmed by the initial results of the pollen analysis of the cores. A relative palaeointensity record has been calculated for the core. It is concluded provisionally that the palaeointensity recorded in the sediments is effected by the astronomical frequencies associated with the precession of the Earth, the eccentricity and the obliquity of the Earth's orbit.
