Paleomagnetism of the Flores volcanics, Vancouver Island, in place by Eocene time
The purpose of this paper is to describe paleomagnetic data from Eocene rocks of the Insular Belt, the westernmost element of the Canadian Cordillera. The possibility of using their paleomagnetism to reconstruct their attitude is considered
500,000-year paleomagnetic record from New Zealand loess
Here the AA. report paleomagnetic data from independently dated loess in New Zealand which spans the last ca. 500,000 years, entirely within the Brunhes Normal Chron. This is the longest continuous sequence described to date and these paleomagnetic
Paleomagnetic evidence for repeated glacial Lake Missoula floods from sediments of the Sanpoil River valley, northeastern Washington
Recent explanations of widespread rhytmically layered sediments in eastern Washington as the result of repeated great floods from glacial Lake Missoula implicitly suggest a paleomagnetic test for validity. This work is an application
Dating Late Pleistocene pluvial events and tephras by correlating paleomagnetic secular variation records from the western Great Basin
Climatic variation ; Great Basin ; Lake level ; Model ; Paleo-environment ; Paleomagnetism ; Pleistocene ; Quaternary ; Tephrochronology ; United States
Paleomagnetic records are used to correlate sedimentary sequences from pluvial Lakes Chewaucan and Russell in the western Great Basin. This correlation is the basis forage control in the relatively poorly dated sequence from Lake Chewaucan
. The paleomagnetic correlation allow the AA. to assign ages to the pluvial episodes and to draw conclusions regarding their temporal relationship to regional climatic events. The ages of six tephras layers contained in the poorly dated sequence are also constrained
Paleomagnetic changes within the Brunhes Epoch in the Basaharc loess profile, Hungary
On the basis of magnetic measurements in the paleosols of the Basaharc loess profile, the application of the paleomagnetic methods for stratigraphic subdivision is presented. This relies on the evaluation of random fluctuations of and tendencies
Paleomagnetic investigation of the Bonneville Alloformation, Lake Bonneville, Utah
Paleomagnetic secular variation in a portion of the Bonneville Alloformation is compared with secular variation in lacustrine sediments in the Mono Basin, California, and with secular variation in Lake Lahontan sediments in the northwestern Great
A paleomagnetic record for the Grande Pile lacustrine sequence deposited during the last interglacial-glacial cycle has been constructed based on continuous sampling of a 15-m-long oriented core (GPXX). The present work is intended to assess
the paleomagnetic reliability of the GP sequence by adding magnetomineralogic analysis and subsequent determination of the magnetic fabric properties.
Paleomagnetic investigation of lake Lahontan sediments and its application for dating pluvial events in the Northwestern Great Basin
A comparison of paleomagnetic secular variation in sediment of Pleistocene Lake lahontan in the northwestern Great basin with secular variation in lake sediment in the Mono Basin, California, indicates that Lake Lahontan was in the valley
sediments emphasizes the need for multiple dating methods when paleomagnetic secular variation is used to date stratigraphy.

Testing the reliability of detrital cave sediments as recorders of paleomagnetic secular variations, Seso Cave System (Central Pyrenees, Spain)
A paleomagnetic study has been carried out on a waterlaid detrital sedimentary sequence within the Seso Cave System (West-Central Pyrenees). The detrital sedimentary sequence is made of autochthonous (piping detached material from the Eocene marls
host rock inside of the cavity) and allochthonous (stream transported sediments from the outside) sediments. The declination and inclination of the paleomagnetic characteristic component of each depth point is compared to the Spanish archeomagnetic
catalog and available geomagnetic models in order to determine the accuracy of these sediments recording the Earth's magnetic field. Results suggest that these sediments poorly record the Earth's magnetic field, however, paleomagnetic inclination shows
similar results between both demagnetizing methods and the inclination is well recorded especially in the younger stream facies. Therefore, the inclination data from the Seso Cave deposit is the first record of the Iberian paleomagnetic secular variation
Paleoclimatic, paleomagnetic and paleogeoidal changes: complexity and interaction in Evolution des atmosphères planétaires et climatologie de la terre=Evolution of planetary atmospheres and climatology of the earth.
France) offers a unique paleoclimatic and paleomagnetic record of the last 130,000years. Several geomagnetic excursions are recorded implying rapid motions at the core/mantle interface. The data reveal a correlation between paleoclimate and the position
of the geomagnetic pole: during ice ages the pole was in the Siberian-Arctic region. There is a close correlation between paleomagnetic and paleogeoid changes implying a mutual origin in core/mantle changes. The astronomical variables in the Earth/Sun constellation
have a double effect, affecting both the insolation and the Earth's rate of rotation. They therefore simultaneously generate changes in paleoclimate, paleomagnetism and paleogeodesy. It is uncertain whether the main paleoclimatic effect comes from
The Blake paleomagnetic event in the Basaharc Double paleosol complex of loess profiles Paks, Mende and Basaharc, Hungary
of loess formation and with the relatively short duration of paleomagnetic intervals within this epoch. One of these intervals is the Blake Event, which corresponds to the Riss/Würm boundary. Through thermoluminescence analyses, this event can be detected
Near East paleomagnetic secular variation recorded in sediments from the Sea of Galilee (Lake Kinneret)
Paleomagnetic records of declination and inclination from sediments recovered from the bed of Lake Kinneret (32.4 N, 37.7 E) have been dated by radiocarbon techniques. The sediments spare the last 5 000 yr. Magnetic susceptibility logs display 13
By analizing the column well core the paleomagnetic properties of 300 meter thick layers of Cenozoic deposits have been determined. Intervals of direct polarity are identified with high degree of certainty in deposits of Komi-Perm subhorizons
as well as in those of Pechora, Rodionovo, Vychegda and Sulino periods. Reverse make any conclusions about the stratigraphy of the surveyed layers, howewer most probably they were formed at Bruness paleomagnetic epoch. -(L'A.).
