Sentences with phrase «magnetic susceptibility of»

Mappings of the geochemistry and magnetic susceptibility of detrital sources in the watershed of the lagoon and from the coastal barriers were undertaken in order to track the terrestrial or coastal / marine origin of sediments deposited into the lagoon.

Not exact matches

All study participants underwent a type of magnetic resonance imaging called susceptibility - weighted imaging that is specifically targeted to better image blood products.

Yet, despite their widespread use, at room temperature only three elements are ferromagnetic — meaning they have high susceptibility to becoming and remaining magnetic in the absence of a field, as opposed to paramagnetic substances, which are only weakly attracted to the poles of a magnet and do not retain any magnetism on their own.

Several magnetic susceptibility phases and trends are recognised and are interpreted in terms of sea - level fluctuations before, during and after the PETM.

investigation of palynofacies and low - field magnetic susceptibility reveal significant detrital influx during the interval.

C: Datasets suggesting a drying environment at 2.5 Ma, shown by λ 18O from benthic foraminifera, a proxy for global temperature, smoothed with a Gaussian window of 200 ky; eustatic sea level; and magnetic susceptibility, a proxy for ice rafted debris and Northern Hemisphere glaciation.

We studied a high - resolution multiproxy data set, including magnetic susceptibility (MS), CaCO3 content, and stable isotopes (δ18O and δ13C), from the stratigraphic interval covering the uppermost Maastrichtian and the lower Danian, represented by the pelagic limestones of the Scaglia Rossa Formation continuously exposed in the classic sections of the Bottaccione Gorge and the Contessa Highway near Gubbio, Italy.

The stratigraphic framework and related age models of the four sediment cores used in this study, are based on oxygen isotope stratigraphy, 10Be stratigraphy, paleomagnetostratigraphy, biostratigraphy, lithostratigraphy, and / or magnetic susceptibility records (Supplementary Figs. 2 — 5).
