A jackknife for magnetostratigraphy
Geophysical Research Letters, 1991 We investigate the problem of evaluating the reliability of a magnetostratigraphic section using a jackknife resampling scheme. We define a parameter, J as the slope relating the percentage of polarity zones of a sampled section remaining after random deletion of sites increasing in proportion to a total of 20% of the initial collection.

Results of magnetostratigraphic study of the Lower Syzran subformation (Paleocene) in the north of the Saratov Right Bank (Gremyachka and Kluchy-2 sections) [PDF]
Известия Саратовского университета. Новая серия: Серия Науки о ЗемлеThe results of petromagnetic and paleomagnetic studies of two sections of the Lower Syzran subformation (Paleocene) – Gremyachka and Klyuchi-2, located in the north of the Saratov Right Bank and represented by weakly magnetic silicites, are ...

Magnetostratigraphic Chronology of a Cenozoic Sequence From DSDP Site 274, Ross Sea, Antarctica
Frontiers in Earth Science, 2020 New paleomagnetic results from the late Eocene-Middle Miocene samples from Deep Sea Drilling Project Site 274, cored during Leg 28 on the continental rise off Victoria Land, Ross Sea, provide a chronostratigraphic framework for an existing paleoclimate ...

Geochemistry, Geophysics, Geosystems, 2022 The Cenozoic tectonic evolution of the southeastern edge of the Tibetan Plateau is interpreted in terms of two alterative dynamic mechanisms: lateral extrusion of coherent lithospheric blocks and viscous lower crustal flow.

Frontiers in Earth Science, 2021 Late Devonian time was a period of rapid upheaval in the Earth system, including climate change, sea level changes, widespread ocean anoxia, and the Frasnian-Famennian mass extinction; the cause(s) of these changes remain(s) uncertain.

Magnetostratigraphy and Radiometric Chronology
The Quaternary Research (Daiyonki-Kenkyu), 1977 This paper briefly reviews the history and present status of magnetostratigraphy, and re-examines the usefulness of magnetostratigraphy in absolute chronology. At present, two different kinds of time scale are used as standards for magnetostratigraphic age determination.

Frontiers in Earth Science, 2022 The Corinth basin (Greece) is a young continental rift that recorded cyclic basin paleoenvironment variations (i.e., marine to lacustrine) caused by glacio-eustatic sea level fluctuations during its initial connection to the global oceans.

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope
Sedimentology, EarlyView.ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.
