Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

Geochemistry, Geophysics, Geosystems
The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions.

Constrained Magnetostratigraphic Dating of a Continental Middle Miocene Section in the Arid Central Asia

Frontiers in Earth Science, 2018
The Neogene succession of the Aktau Mountains in the Ili Basin, southeast Kazakhstan, is a terrestrial archive well suited for researching the role of Central Asia in Miocene climate evolution.

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 ...

Magnetostratigraphic and biostratigraphic synthesis of ocean drilling program Leg 105: Labrador Sea and Baffin Bay [PDF]

, 1989
During Ocean Drilling Program (ODP) Leg 105, three sites (Sites 645 through 647) were drilled in Baffin Bay and the Labrador Sea to examine the tectonic evolution and the climatic and oceanic histories of this region.

Chronostratigraphy and tectono‐sedimentary history of the Eastern South Pyrenean foreland basin (Ripoll Syncline, North‐East Spain)

The Depositional Record
This paper contributes to an understanding of the tectono‐sedimentary evolution of the South Pyrenean foreland system by reviewing the chronostratigraphic framework of the basin infill in its eastern sector. Six sections are analysed and cross‐correlated

Paleomagnetic constraints on the age of the Botucatu Formation in Rio Grande do Sul, southern Brazil

Anais da Academia Brasileira de Ciências, 2006
Paleomagnetic and rockmagnetic data are reported for the aeolian Botucatu Formation, in the southern Brazilian State of Rio Grande do Sul. Oriented samples were taken from a section located between the cities of Jaguari and Santiago.

A greigite-based magnetostratigraphic time frame for the Late Miocene to Recent DSDP Leg 42B cores from the Black Sea

Frontiers in Earth Science, 2016
Throughout the Late Neogene, the Black Sea experienced large paleoenvironmental changes, switching between (anoxic) marine conditions when connected to the Mediterranean Sea and (oxic) freshwater conditions at times of isolation.

Magnetostratigraphy of the Lower Carboniferous [PDF]

, 2020
Geomagnetic polarity reversals studied by magnetostratigraphy have been described well in the Cenozoic and Mesozoic, unfortunately, there are still many data gaps in the Palaeozoic where the magnetostratigraphic record is not easy to correlate or is unknown. One of those is during the Carboniferous System. The magnetostratigraphy of Carboniferous rocks

Magnetostratigraphy

, 2018
Magnetostratigraphy uses the fossil record of Earth's magnetic polarity reversals to correlate rock sequences. Dating is also possible through correlation to age‐calibrated geomagnetic polarity time scales.
