Evidence for Asteroid Scattering and Distal Solar System Solids From Meteorite Paleomagnetism

open access: yesAstrophysical Journal, 2020
Asteroid-sized bodies are predicted to have been scattered throughout the solar system following gravitational interactions with the giant planets. This process could have delivered water-rich small bodies to the inner solar system.

An ultra-low magnetic field thermal demagnetizer for high-precision paleomagnetism

open access: yesEarth, Planets and Space, 2020
Thermal demagnetization furnaces are widely used paleomagnetic facilities for progressive removal of naturally acquired magnetic remanence or the imparting of well-controlled laboratory magnetization.

Role of Paleomagnetism in the Construction of Earth’s Geographic Past

open access: yesUndergraduate Journal of Mathematical Modeling: One + Two, 2020
Rocks have the ability to preserve magnetic information used in determining past geographic formations. The purpose of this report is to determine the past location of a site from a given data set’s magnetic information and the calculations found through

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

Lifetime of the solar nebula constrained by meteorite paleomagnetism

open access: yesScience, 2017
Meteorite magnetism in the early solar system The young solar system contained a disc of gas and dust within which planet formation occurred. The disc eventually dissipated after the Sun ignited and the planets formed, but exactly when that happened has ...
