Formation of ultrafine-grained magnetite in soils

  title={Formation of ultrafine-grained magnetite in soils},
  author={B. Maher and R. Taylor},
The magnetic properties of certain soils indicate the widespread presence of ultrafine-grained magnetite, even where there is no detrital input of magnetite1–3. This suggests that in situformation of magnetite can occur under soil-forming conditions. Schwertmann and Taylor4 have stated, however, that magnetite has not been found as a newly formed mineral in soils. Here we report the recovery and identification of pure, ultrafine-grained magnetite from some UK soils that have no apparent… Expand
Occurrence of magnetic bacteria in soil
It is suggested that magnetic bacteria and their magnetofossils14 can contribute to the magnetic properties of soils. Expand
Inorganic Formation of Ultrafine-Grained Magnetite
Within the last 15–20 years, an increasing number of environmental scientists have become interested in investigating the magnetic properties of a range of earth surface materials, from atmosphericExpand
Structural and Morphological Characterization of Biogenic Magnetite Crystals
The biological form of the ferrimagnetic mineral, magnetite, was discovered in molluscs (polyplacophora) by Lowenstam (1962). Marine molluscs such as chitons use a specialized tongue or radula, whichExpand
Magnetic enhancement is linked to and precedes hematite formation in aerobic soil
[1] Soil formation usually increases magnetic susceptibility, most often by increasing the concentrations of magnetite and maghemite, which are two ferrimagnetic iron oxides. Here we provide evidenceExpand
Factors Controlling Magnetism of Reddish Brown Soil Profiles from Calcarenites in Southern Spain: Dust Input or In-situ Pedogenesis?
Under aerobic conditions, the A and B horizons of soils are magnetically enhanced due to neoformation of ferrimagnets through pedogenesis. This study systematically investigated soils developed onExpand
Magnetite originating from bonfires in a Brazilian prehistoric Anthrosol: A micro-Raman approach
Abstract Soils within archaeological sites may show magnetic properties due to the presence of magnetic minerals, such as magnetite and maghemite, which form during deposition of the soil or due toExpand
Biogenic magnetite and the magnetization of sediments
Biogenic magnetites are produced through the reduction of ferric iron by both biologically induced (extracellular) and biologically controlled (intracellular) processes. With few exceptions, all areExpand
The Source of Fine-Grained ‘Magnetite’ in Sediments
Extensive study of the magnetic properties of soils and sediments by both earth scientists and biomagnetists has failed to establish the extent to which fine-grained magnetic components in theExpand
Magnetic Properties of Soils
Iron-containing minerals, i.e., magnetic minerals, constitute an intimate part of a soil. These can be derived from the parent rock from which the soil developed, or can be formed in situ, or can beExpand
Storage diagenesis versus sulphide authigenesis: possible implications in environmental magnetism
Experiments involving the gradual drying out of controlled mixtures of soil and organic lake sediment during storage at room temperature show that this leads to a loss of magnetic susceptibility andExpand


Magnetotactic bacteria and single-domain magnetite in hemipelagic sediments
Remanent magnetism in marine sediments has been used extensively over the past twenty years to calibrate the geological time-scale, study geomagnetic reversals and secular variation, and measure theExpand

Characterisation of soils by mineral magnetic measurements
Processes of iron mineral authigenesis, diagenesis, and dissolution, in interaction with primary inputs of iron minerals, act to produce vertical differentiation of soil magnetic properties. Thus,Expand
Anaerobic production of magnetite by a dissimilatory iron-reducing microorganism
The potential contribution of microbial metabolism to the magnetization of sediments has only recently been recognized. In the presence of oxygen, magnetotactic bacteria can form intracellular chainsExpand
Magnetic properties of some synthetic sub-micron magnetites
The grain size dependence of various mineral (rock) magnetic parameters has been determined, using a series of essentially pure, fine-grained (single domain, SD) and ultrafine-grainedExpand
Fossil bacterial magnetite in deep-sea sediments from the South Atlantic Ocean
The magnetostratigraphy of deep-sea sediment cores has proven to be a powerful and high-resolution method of dating and comparing sedimentary records. In contrast to this widespread application,Expand
A preliminary magnetic study of soil samples from west-central Minnesota
Abstract Various rock magnetic techniques were applied to characterize magnetically the samples of a soil profile taken from west-central Minnesota. There is a marked change in magnetic properties asExpand
Occurrence and Formation of Iron Oxides in Various Pedoenvironments
The most likely occasion that soil scientists will come in contact with Fe oxides is when they note and try to explain the colors of soils. Many of these soil colors, notably those between red,Expand

Transmission electron microscope and rock magnetic investigations of remanence carriers in a Precambrian metadolerite
A Precambrian metadolerite dyke has two distinct types of remanence carriers; those with medium/high coercivities (unblocking fields of 20–120 mT) and those with low coercivities (unblocking fieldsExpand
