3D Joint Inversion of Scanning Magnetic Microscopy Data
(Journal article; Peer reviewed, 2021)Scanning magnetic microscopy (SMM) is a modern magnetometry technique that maps the magnetic anomalies resulting from small-scale variations of remanent magnetization within a sample. This information is vital to understand ... -
Magnetic phases in hemo-ilmenite: Insight from low-velocity and high-field Mössbauer spectroscopy
(Journal article; Peer reviewed, 2007)[1] We have studied natural samples of hemo‐ilmenite (ilmenite with hematite exsolution lamellae) by use of Mössbauer spectroscopy. The samples are from the Allard Lake intrusion in Quebec. The stoichiometric compositions ... -
Magnetic properties of anorthosites: A forgotten source for planetary magnetic anomalies?
(Journal article; Peer reviewed, 2008)[1] Anorthosites, igneous rocks very rich in plagioclase, rarely considered to be strongly magnetic, are common on Earth, and the Moon, and inferred to be on other planets. Magnetic properties of anorthosites could be ... -
Micromagnetic Modes of Anisotropy of Magnetic Susceptibility in Natural Magnetite Particles
(Peer reviewed; Journal article, 2022)Anisotropy of magnetic susceptibility (AMS) is commonly used to assess sedimentation, deformation, tectonics, rock fabric, and texture. Using focused-ion beam nanotomography, we develop a micromagnetic method to investigate ... -
Mineral Magnetic Characterization of High-Latitude Sediments From Lake Levinson-Lessing, Siberia
(Peer reviewed; Journal article, 2021)Levinson-Lessing Lake in northern Central Siberia is a sedimentary archive characterized by continuous, widely constant sedimentation at high rates (0.7 m ka−1 for >32 ka). This study provides the first evidence of the ...
