“…These investigations were useful in examining paleomagnetic secular variation (PSV) at different localities and periods (e.g. Elwood, 1971;Kopper and Creer, 1973;Creer and Kopper, 1974;Papmarinopoulous and Creer, 1983;Nöel and Thistlewood, 1989;Schmidt and Partridge, 1991). These studies also allowed the observation of geomagnetic field (GF) excursions and reversions (e.g.…”

Palaeomagnetic studies were carried out in several archaeological and palaeontological sites across Argentina and Chile. Remanence directions far removed from the present magnetic field, probably corresponding to a field excursion were recorded in several stratigraphic sections spaning ∼11 to 2 ky bp. Detailed palaeomagnetic data from 235 cores obtained in six sections from archaeological sites in Argentina are reported. Stability of the NRM was analyzed by progressive thermal and alternating field demagnetization and ChRM directions determined in most cases. Computed VGPs from those directions tend to be concentrated over North America, Europe, Eastern Asia and Africa. Using 275 VGPs a palaeomagnetic pole that is ∼20• apart from the Earth's rotation's axis was obtained.

“…is first large-scale attempt to use palaeomagnetism and magnetostratigraphy for dating of cave fill resulted in the spread of the method over the world. Noel and Bull (1982) studied sediments from Clearwater Cave (Mulu, Sarawak, Malaysia). Reversal in Early Quaternary deposits was detected by Noel, Shaw & Ford (1984) in Mason Hill (Derbyshire, Great Britain).…”

“…Very shortly a er the first applications of paleomagnetism in caves, general comments, definitions of limits and thresholds appeared (e.g., Homonko 1978;Stober 1978, Papamarinopoulos 1978Noel 1982Noel , 1985Papamarinopoulos & Creer 1983;Noel & istlewood 1989;Ellwood 1999). Verosub (1977) and Noel (1986b) determined that clastic sediments can suffer much post-depositional alteration of the declination and inclination signals, especially if they have drained.…”

“…Verosub (1977) and Noel (1986b) determined that clastic sediments can suffer much post-depositional alteration of the declination and inclination signals, especially if they have drained. Noel & Bull (1982) suggested that bioturbation of sediments may also be a major problem. Williams et al (1986) emphasised that carriers of remanent magnetisation are usually detrital grains of magnetite.…”

FOREWORD is book reports on the ten years long collaboration of theSlovene Karst Research Institute ZRC SAZU at Postojna with the Institute of Geology, Academy of Sciences of the Czech Republic at Praha (Prof. Pavel Bosak). e last institution has taken 2007 samples of sediments in the 21 profiles of the Slovene Dinaric and Alpine karst and determined their palaeomagnetism and magnetostratigraphy. e oldest sample found in them with the age from about 1.8 to more than 5.4 Ma indicated the surprising age of a cave near the Adriatic seashore. is is the time of the upper Miocene! Toward NE of the Slovene Dinaric Karst this age is diminishing but is still 0.78 Ma in the Postojnska jama. In one of the three researched high Alpine caves in the northern Slovenia this age is between 1.2 and 5.0 Ma.e study proved that the cave sediments represent a good tool for the reconstruction of the landscape evolution and tectonic regime in different karst regions. In collaboration with the team from Bohemia, the Slovene scientists added the results of research in many natural sciences on the Slovene caves and karst regions, already published or not yet published in the Slovenian and in the foreign literature. is is why this monograph on the Slovene karst caves and Slovene karst gives many new information. e famous French speleologist E. Martel in his book Les Abîmes in the year 1894 confirms the reputation of the Slovene Dinaric region Kras (Karst) by naming it "the classical karst" as here investigations of hydrology and caves started. e present book has repeated this reputation.Research in the Slovene caves contributed also to the improvement of the techniques of sampling for high resolution approach of fine cave sediments with dense sample spacing.e book is therefore important also for technology of sampling and for applying the palaeomagnetism and magnetostratigraphy for the karst sediments.
