Magnetostratigraphy concepts, definitions, and applications

Newsletters on Stratigraphy, 2010
The most characteristic feature of the Earth's magnetic field is that it reverses polarity at irregu- lar intervals, producing a 'bar code' of alternating normal (north directed) and reverse (south directed) polar- ity chrons with characteristic durations.

The magnetostratigraphy of Leg 73 sediments

Palaeogeography, Palaeoclimatology, Palaeoecology, 1983
Abstract The main objectiveof DSDP Leg 73 was to obtain high-quality records of major paleooceanographic events in the South Atlantic. This was achieved by coringsix sites on the African plate. The sediments thus recovered span the Cenozoic and five of the six sites proved ideally suited for magnetostratigraphic analysis.

A coherent middle Pliocene magnetostratigraphy, Wanganui Basin, New Zealand

Journal of the Royal Society of New Zealand, 2005
We document magnetostratigraphies for three river sections (Turakina, Rangitikei, Wanganui) in Wanganui Basin and interpret them as corresponding to the Upper Gilbert, the Gauss and lower Matuyama Chrons of the Geomagnetic Polarity Timescale, in ...

Carboniferous magnetostratigraphy

Journal of the Geological Society, 1985
A review of the available data on the polarity of the geomagnetic field during the Carboniferous confirms that it is predominantly reversed, although the data base is only of poor reliability, particularly in terms of the age of the magnetization. New British and Irish data, partially supported by positive fold tests, suggest that the Courceyan and ...

Magnetostratigraphy

Geology Today, 1987
Magnetostratigraphy involves the study of changes in the Earth's magnetic field that are recorded in sediments and rocks. These include short‐term fluctuations (secular variation), polarity transitions and magnetic reversal sequences. All have important applications in the Earth sciences.

Quaternary magnetostratigraphy in Denmark

Boreas, 1987
Magnetostratigraphical results from various historical, Holocene, Lateglacial and Glacial deposits from Central Jutland, Vendsyssel, the Baltic Sea and Schleswig‐Holstein are illustrated and discussed. Although only a few archaeomagnetic case studies have yet been made in Denmark, magnetic datings with accuracies of about ±50 years have been obtained ...

Magnetostratigraphy

Magnetostratigraphy is a stratigraphic technique that utilizes the magnetic properties of rocks to establish chronological frameworks and correlate stratigraphic sections across geological time. It is based on the premise that rocks retain a record of the Earth’s magnetic field at the time of their formatio-n.

Magnetostratigraphy of Vindhyan Supergroup

Journal Geological Society of India, 1996
Abstract In the absence of conventional radiometric dating and fossil evidence, magnetostratigraphy is considered to be a very powerful tool to correlate rock formations. Often the magnetozones are used as bench marks in correlation of rocks as the geomagnetic field reversals are ubiquitously synchronous.

Mammals and Magnetostratigraphy

Journal of Geological Education, 1988
Magnetic polarity stratigraphy has become one of the most important tools for correlation of fossiliferous terrestrial deposits. Since 1975, many of the suitable fossiliferous terrestrial vertebrate-bearing sequences in North America, Eurasia, South America, and Africa, have been correlated with the magnetic polarity timescale.
