Special Issue Information

Dear Colleagues,

The aim of the Special Issue is to provide an up-to-date summary of research in Environmental Magnetism. Current topics in the field includes advances in techniques related to the availability of new instrumentation or new knowledge about mineral magnetism, as well as a wide range of applications in which magnetic measurements are used, often alongside other techniques, to shed light on issues such as human impact on landscapes, climate change, sediment and dust sourcing, sediment diagenesis and particulate pollution. Much of this work rests on gaining the best possible insight into the magnetic mineralogy and grain size variations responsible for the properties recorded. The magnetic mineralogy of environmental materials such as sediments, dusts and soils, both modern and fossil, is often complex: therefore, contributions that advance the interpretation of natural magnetic mineral assemblages will be especially welcome. Contributions are also invited that highlight progress in the applications of the methodology to addressing environmental problems.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 300 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

Title: Burial diagenesis of magnetic minerals: new insights from the Grès d’Annot transect (SE, France)
Author:
Myriam Kars, Charles Aubourg, Pierre Labaume and Thelma S. Berquo
Abstract:
Diagenetic evolution of the magnetic minerals during burial in sedimentary basins has been recently proposed. In this study, we provide new data from the Grès d’Annot basin, SE France. We analyzed fine-grained clastic rocks that suffered burial temperature from ~60 to > 250°C, i.e. covering oil and gas windows (Ro~0.5% to >7%). Low temperature magnetic measurements (10-300 K), coupled with vitrinite reflectance values, aim at defining the magnetic minerals evolution through the burial history. Magnetite is evidenced throughout the entire studied transect. Goethite, probably occurring as nanoparticles, is found for temperature <80°C. Micron-sized pyrrhotite is highlighted for temperature > 200°C below the Alpine nappes and the Penninic Front. A model of evolution of the magnetic assemblage from 60 to > 250°C is proposed for clastic rocks. This work provides the ground for a better understanding of magnetic properties of petroleum plays.

Title:
Magnetic signature of anthropogenic pollution of soil and correlation with heavy metals in the broader Kozani–Ptolemaida region, Northern Greece
Author: Irene Zananiri, Simo Spassov, Despina Kondopoulou, Andy Gault, David Polya, Artemios Atzemoglou and Barbara Maher
Abstract:
Since 1951, the character of Greece has changed from a mainly agricultural into a more industrial country. In the course of the economic revival, this change implied a rapid development of urban and industrial areas, resulting in serious consequences for the Hellenic environment. The present study focuses on fly ash and heavy metal pollution, one of the major environmental problems of the broader Kozani – Ptolemaida region (northern Greece) where five power plants are operating. The target of the project was twofold: (a) to challenge the correlation between ferrimagnetic mineral content and geochemical properties of samples from polluted areas, (b) to estimate the spatial distribution of several pollutants within the study area. Towards this scope, the magnetic susceptibility was mapped using a Bartington susceptibility meter (MS2D-loop) with a resolution of 1×1 km, and soil samples were collected from each measurement point. After drying and sieving, the specimens were subjected to several laboratory experiments: measurement of magnetic low-field susceptibility at low and high frequency, isothermal remanence acquisition, thermomagnetic analyses, alternating field demagnetization of both natural and isothermal remanent magnetization, anhysteretic remanence experiments and hysteresis loops. The concentrations of Fe, Mn, Cr, Cu, Pb and Zn in the studied soils were determined by X-ray fluorescence and ICP-AES analyses were carried out on HNO3 digests from the same samples. The in-situ susceptibility values exhibit significant variation, ranging from very low background values (7×10-5 SI) to high values (730×10-5 SI), with a mean of 141×10-5 SI. The same variation arises from laboratory susceptibility measurements at low and high frequency, with a mean frequency dependence (F-factor) of 5 %. Preliminary geochemical measurements indicate concentrations of 40-360 mg(Cr3+)/kg, 10-30 mg(Cu)/kg, 3523-21543 mg(Fe)/kg, 195-1150 mg(Mn)/kg, 46-471 mg(Ni)/kg, 3-25 mg(Pb)/kg and 19-70 mg(Zn)/kg. An excellent linear correlation was found between magnetic susceptibility and the concentrations of soil Fe, Mn, Cu and Pb, whereas the correlation between magnetic susceptibility and concentration of Zn and Cr3+ in soil was poor, suggesting that the pollutants are physically not related to the magnetic minerals.
