Rock magnetism and soil magnetic susceptibility [PDF]

open access: diamondAgrochemistry and Soil Science, 2021
Information support of modern agriculture and ecology forms a demand for ever higher requirements for efficiency and density of the sampling network. This fact determines the spread of high-performance methods of soil research, among which are magnetometric ones. However, these methods have a number of limitations associated with the existence in soils

Late Paleozoic Depositional Environments and Sediment Transport Directions of the Itararé Group Rocks From the State of São Paulo, Brazil, Determined From Rock Magnetism and Magnetic Anisotropy [PDF]

open access: goldEarth and Space Science, 2021
Sedimentary rocks of the Itararé Group, deposited during the Late Paleozoic Ice Age in the Paraná Basin of South America, were collected throughout the state of São Paulo, Brazil, for an anisotropy of magnetic susceptibility (AMS) and rock‐magnetic study.

The importance of clays in speleothem magnetic remanence acquisition [PDF]

open access: yesScientific Reports
Speleothems are promising recorders of paleosecular variation of the Earth’s magnetic field, but ambiguities remain about the physical processes active during remanence acquisition.

Magnetic Properties of Plant Ashes and Their Influence on Magnetic Signatures of Fire in Soils

open access: yesFrontiers in Earth Science, 2021
Fires are an integral part of many terrestrial ecosystems and have a strong impact on soil properties. While reports of topsoil magnetic enhancement after fires vary widely, recent evidence suggests that plant ashes provide the most significant source of

Magnetic Mineralogy of Speleothems From Tropical-Subtropical Sites of South America

open access: yesFrontiers in Earth Science, 2021
Fe-bearing minerals are a tiny fraction of the composition of speleothems. They have their origin in the karst system or are transported from the drainage basin into the cave.
