The Effect of Differential Weathering on The Magnetic Properties of Paleosols: A Case Study of Magnetic Enhancement vs. Magnetic Depletion in the Pleistocene Blackwater Draw Formation, Texas

open access: yesFrontiers in Earth Science, 2021
The type-section of the Blackwater Draw Formation (BDF) consists of a series of five paleosol horizons developed on eolian deposits and an overlying surficial soil. Previous work has shown that magnetic properties (e.g., χ, ARM, and IRM) as a function of

Paleoclimatic and provenance implications of magnetic parameters from the Miocene sediments in the Subei Basin

open access: yesEarth and Planetary Physics, 2020
Thick sediments from foreland basins usually provide valuable information for understanding the relationships between mountain building, rock denudation, and sediment deposition.

Evergreen Needle Magnetization as a Proxy for Particulate Matter Pollution in Urban Environments

open access: yesGeoHealth, 2020
We test the use of magnetic measurements of evergreen needles as a proxy for particulate matter pollution in Salt Lake City, Utah. Measurements of saturation isothermal remanent magnetization indicate needle magnetization increases with increased air ...

Interpreting high-temperature magnetic susceptibility data of natural systems

open access: yesFrontiers in Earth Science, 2023
High-temperature susceptibility (HT-χ) data are routinely measured in Earth, planetary, and environmental sciences to rapidly identify the magnetic mineralogy of natural systems. The interpretation of such data can be complicated.

The identification and biogeochemical interpretation of fossil magnetotactic bacteria [PDF]

open access: yes, 2008
Magnetotactic bacteria, which most commonly live within the oxic-anoxic transition zone (OATZ) of aquatic environments, produce intracellular crystals of magnetic minerals, specifically magnetite or greigite.

Holocene evolution of the Banni Plain at the north‐east margin of the Arabian Sea: Constraints from a ca 50 m long sediment core

open access: yesThe Depositional Record, 2023
Holocene evolutionary history of the Banni Plain in the Great Rann of the Kachchh Basin is reconstructed from a subsurface sediment core of ca 50 m. Detailed data on textural and lithofacies variations, grain‐size analysis, environmental magnetism and ...

GEOMAGNETIC EXCURSION RECORD PRESERVED IN THE SPELEOTHEM FROM WESTERN CAUCASUS: FIRST DATA

open access: yesГеодинамика и тектонофизика, 2022
The study of the geomagnetic field evolution on minor timescales, in particular of such significant events as geomagnetic reversals and excursions, has acquired particular relevance nowadays due to the increased attention of mankind to the environment ...

Magnetic Biomonitoring as a Tool for Assessment of Air Pollution Patterns in a Tropical Valley Using Tillandsia sp.

open access: yesAtmosphere, 2018
Recently, air pollution alerts were issued in the Metropolitan Area of Aburrá Valley (AVMA) due to the highest recorded levels of particulate matter (PM2.5 and PM10) ever measured. We propose a novel methodology based on magnetic parameters and an

Biomagnetic Characterization of Air Pollution Particulates in Lahore, Pakistan

open access: yesGeochemistry, Geophysics, Geosystems, 2022
We report the characterization of anthropogenic magnetic particulate matter (MPM) collected on leaves from roadside Callistemon (bottlebrush) trees from Lahore, Pakistan, and on known sources of traffic‐related particulates to assess the potential of ...
