Age and Magnetism of Cave Sediments from Postojnska jama cave system and Planinska jama cave, Slovenia
Stanka Šebela,Ira D. Sasowsky - (28/2,1999)
We completed paleomagnetic analyses of 28 samples of cave sediments from 3 different locations in Postojnska jama cave system and one location in Planinska jama cave. These are the first published paleomagnetic studies of cave sediments from these caves. These sediments showed normal polarity, and were deposited during the Brunhes Normal Epoch (younger than 0,73 Ma). However, an additional more complex sediment deposit in an upper section of the Postojnska jama cave system, showed reverse polarity, probably indicating an age between 0,73 and 0,90 Ma.
