Worldwide database for magnetostratigraphy available [PDF]

Eos, Transactions American Geophysical Union, 1998
The International Association of Geomagnetism and Aeronomy (IAGA) has sponsored the development of databases in paleomagnetism and rock magnetism. The databases operate under Microsoft Access V2.0 (for Windows 3.1) or Access 97 (for Windows 95) [McElhinny and Lock, 1996].

Palaeomagnetic and synchrotron analysis of >1.95 Ma fossil-bearing palaeokarst at Haasgat, South Africa

South African Journal of Science, 2014
Palaeomagnetic analysis indicates that Haasgat, a fossil-bearing palaeocave in the Gauteng Province of South Africa, is dominated by reversed magnetic polarity in its oldest, deepest layers and normal polarity in the younger layers.

Expedition 306 summary

, 2006
The overall aim of the North Atlantic paleoceanography study of Integrated Ocean Drilling Program Expedition 306 is to place late Neogene–Quaternary climate proxies in the North Atlantic into a chronology based on a combination of geomagnetic ...

Sedimentation rates in the Makarov Basin, central Arctic Ocean: A paleomagnetic and rock magnetic approach [PDF]

, 2001
Three long sediment cores from the Makarov Basin have been subjected to detailed paleomagnetic and rock magnetic analyses. Investigated sediments are dominated by normal polarity including short reversal excursions, indicating that most of the sediments ...

Modeling magnetostratigraphy in a borehole [PDF]

GEOPHYSICS, 1989
The magnetic field along a hole bored through a sequence of dipping layers with varying magnetization and planar interfaces is calculated. The emphasis is on recovering remanent magnetization polarity transitions for magnetostratigraphic applications (dating, correlations), although intensity of remanent magnetization can in itself be a useful rock ...

New Phoenix Magnetic Anomaly Data Confirms Global Nature of Jurassic Quiet Zone and Provides Insight Into Early Pacific Spreading

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...

Quaternary high latitude magnetostratigraphy [PDF]

Polar Research, 1987
Magnetostratigraphic dating of Quaternary sediments is in general exclusively based on the identification of the Brunhesl Matuyama boundary and the Jaramillo and Olduvai Subchrons within the Matuyama Chron. Mounting evidence suggests, however, that short excursions or reversal events of the earth's field have also occurred during the Brunhes Chron ...

Birth, life and death of the Pannonian Lake [PDF]

, 1990
The Miocene-Pliocene Pannonian Lake formed in an extensional basin system behind the compressional arc of the Carpathians. Its size and depth were comparable to those of the Caspian Sea.

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...
