In anisotropic materials such as minerals and rocks, the AC magnetic susceptibility is also anisotropic, and consists of two components, one in-phase with the applied field (ipMS) and the other out-of-phase (opMS). Correspondingly, anisotropies of th

The Jurassic/Cretaceous transition was accompanied by significant changes in palaeoceanography and palaeoenvironments in the Tethyan Realm, but outside the Tethys such data are very scarce. Here we present results of a study of the most complete sect

Magnetic susceptibility (both in-phase, ipMS, and out-of-phase, opMS, components) and its anisotropy were investigated in artificial specimens with pure synthetic magnetite and in rocks with titanomagnetite with variable Ti-content reaching XUsp = 0.

24 brick samples for archaeomagnetic studies were taken from teen historical buildings constructed between c.1280 AD and 1630 AD in northern Poland. Eight of them are from the gothic period. The Thellier-Thellier archaeointensity protocol was used in

SUMMARY As shown in the literature several times, the calculation of the anisotropy of magnetic susceptibility (AMS) of hematite single crystals using standard linear AMS theory reveals that the calculated minimum principal susceptibility is parallel

In this contribution, we present a rock magnetic and magnetic fabric study of the Dejvice loess/paleosol sequence with an aim to demonstrate how rock magnetic methods can be very effective tools for detecting paleoenvironmental, pedogenic, and post-d

Out-of-phase component of AC magnetic susceptibility (opMS) in four single crystals of hematite from Minas Gerais, Brazil was investigated. The phase angle ranges from 1° to 6° along the c-axis and slightly exceeds 25° along the basal plane (in th

The magnetic fabrics in sedimentary, volcanic, and plutonic rocks primarily originate during deposition, lava or ash flow, and magma flow, respectively. During later rock development, these magnetic fabrics can be overprinted by various processes amo

The growing interest in ferromagnetic fabric, i.e. magnetic fabric carried solely by ferromagnetic (sensu lato) grains, creates the need for a simple way to obtain anisotropy of magnetic remanence (AMR) tensors from a set of laboratory imparted, spat
