Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”

open access: yesGeophysical Monograph Series, Page 449-486., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

New data concerning the early middle miocene on the southern slopes of Fruška Gora (Northern Serbia): A case study from the Mutalj quarry [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2011
During the last few years, geological research at the southern slopes of Fruška Gora Mt. enabled the discovery of different Miocene units (undivided the Lower Miocene and Middle Miocene Badenian, predominantly). This is primarily thinking of the

A strong angular dependence of magnetic properties of magnetosome chains: Implications for rock magnetism and paleomagnetism

open access: yesGeochemistry, Geophysics, Geosystems, 2013
Single‐domain magnetite particles produced by magnetotactic bacteria (magnetosomes) and aligned in chains are of great interest in the biosciences and geosciences. Here, we investigated angular variation of magnetic properties of aligned Magnetospirillum

A Smaller Greater India and a Middle‐Early Eocene Collision With Asia

open access: yesGeophysical Research Letters, 2023
When and how the collision between India‐Asia occurred continue to be debated. We report new paleomagnetic data (Ds = 158.8°, Is = 7.8°, ks = 81.3, α95 = 5.1°, N = 11 sites) from limestone of the Zongpu Formation Member I in the Tingri, which indicate ...

Experimental Evaluation on the Heating Efficiency of Magnetoferritin Nanoparticles in an Alternating Magnetic Field

open access: yesNanomaterials, 2019
The superparamagnetic substance magnetoferritin is a potential bio-nanomaterial for tumor magnetic hyperthermia because of its active tumor-targeting outer protein shell, uniform and tunable nanosized inner mineral core, monodispersity and good ...

New paleomagnetic data on the Permian-Triassic sedimentary sections of the Moscow syneclise

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2020
The results of a detailed paleomagnetic study of the following five Permian-Triassic sections of the Russian Platform were discussed: Slukino (Vladimir region), Sartakovo and Prudovka (Nizhny Novgorod region), Klykovo and Gavrino (Vologda region).

Bias Corrected Estimation of Paleointensity (BiCEP): An Improved Methodology for Obtaining Paleointensity Estimates

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The assumptions of paleointensity experiments are violated in many natural and archeological materials, leading to Arai plots which do not appear linear and yield inaccurate paleointensity estimates, leading to bias in the result.

New Paleointensity Data From Aniakchak Volcano, Alaska, USA

open access: yesGeochemistry, Geophysics, Geosystems, 2021
This study presents the first set of Holocene, high‐quality absolute paleointensity data from Alaska, USA. Existing paleointensity data for the Holocene are generally located at mid‐northern latitudes in North America, Europe, the Middle East, and ...

Rock magnetic investigations constraining relative timing for gold deposits in Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 2011
Palaeomagnetic and anisotropy of magnetic susceptibility (AMS) studies were carried out on a orogenic gold deposit in Jokisivu, located in the western part of the Pirkanmaa Belt in the Svecofennian domain of southern Finland.
