The study of magnetization of the ceramic material from 21 archeological monuments of Portugal (the Evora province), dated archeologically from the Bronze Age to the end of the Iron Age has been carried out. For the purpose of more detailed timing of the material from the monuments the method of ceramic age dating on the basis of its porosity has b...

Samples of different rocks, which possess high values of the anisotropy of magnetic susceptibility, were studied by the magneto-mineralogical and optical methods and by microprobe analysis. It was established that for the samples, which contain the pseudo-single-domain ferromagnetite elongated particles, the source of the anisotropy of magnetic sus...

The genesis, varve, and paleomagnetic informativeness of glaciolacustrine sediments are considered based on paleomagnetic and lithological studies. The magnetic properties of varved clays from periglacial basins have been considered using the sedimentological model of formation of varved clays as products of glacial turbidity currents, which explai...

Paleomagnetic researches of the Upper Cretaceous rocks, collected from 24 cross-sections (530 samples) of Georgia have shown that only nine samples are suitable for the paleotectonic problem to be solved. The method of thermomagnetic cleaning was used for the paleomagnetic directions of these rocks to be determined. Magnetic-mineralogical data and ...

We performed wavelet analysis of series of the magnetic field intensity obtained through archaeomagnetic studies in Bulgaria, Georgia, Central Asia, China, and Japan. The duration of the studied intervals is 2000, 4000, and more than 7000 yrs. It has been shown that periodic oscillations as well as those with varying characteristic times are presen...

We analyze the results of wavelet analysis of series of archaeomagnetic data on the geomagnetic field’s intensity over the past 7500 yrs performed by Gurarii and Aleksyutin and presented in the paper “Wavelet Analysis of Basic Archaeomagnetic Series of Data on Geomagnetic Field Intensity over the Past 7500 Years” [Gurarii and Aleksytin, 2009]. The ...

The paleomagnetic study of the Lower Ordovician and Cambrian sedimentary rocks exposed on the Narva River’s right bank revealed a multicomponent composition of natural remanent magnetization. Among four distinguished medium- and high-temperature magnetization components, the bipolar component, which carries the reversal test, is probably the primar...

The paper is concerned with the detailed sectional petromagnetic study of boundary clay in four 1A, 1B, 2A, and 2B Gams sections (in Austria). The composition of basic magnetic minerals in the boundary clay of all sections is similar. They are composed of iron hydroxides, hemoilmenite, titanomagnetite, magnetite, hematite, and iron. The difference ...

Paleomagnetic investigations of marine and subaqueous deposits in the 12-meter marine terrace of a section of the Karadzha Range (Azerbaijan) are performed. These deposits correspond to OI stage 3 and encompass the time interval ∼45–20 ka. Four anomalous deviations of the magnetization from the dipole field at the sampling site are recorded in the ...

In the present paper the new petro- and paleomagnetic data on the Jurassic terrigenous complexes of the Mesozoic sedimentary basins of the Amur River region, Trans Baikal region, and Yakutia are presented. The magnetic properties of the sedimentary rocks of coastal-marine (paleo-shelf) and lake genesis are investigated in the contemporary intracont...
