Special Issue Information

Dear Colleagues,

Soils play essential roles in most of Earth’s processes due to their participation in global climate regulation and main biogeochemical cycles. These involve pedogenetic processes that transform rocks and sediments, whose characteristics are influenced by combinations of soil formation factors such as the source material, climate, microorganisms, and time. Soil organic matter (SOM) has a particularly important role in environmental sustainability, since it is related to carbon and nutrient cycling, and it is a crucial factor to consider in studies related to global climate change and agronomy. Thus, studies aiming to understand the dynamics, interactions and processes that occur in soil and sediments, based on minerals and organic matter, as well as its humic fractions, are fundamental for the evaluation of quality and stability of soil and sediment in changes over time.

This Special Issue of Minerals, entitled “Analytical Spectroscopic Techniques: Applications on Minerals and Organic Matter in Soils and Sediments”, will focus on the fundamentals and applications of geochemical processes that occur in soils and sediments.

Contributions focused on new innovative and portable techniques and/or methods for applications in soils, sediments, water, environmental monitoring, and geochemical processes are encouraged. The scope of this Special Issue includes, but is not limited to, the following topics: flame atomic absorption spectrometry (FAAS), inductively coupled plasma-optical emission spectrometry (ICP-OES), inductively coupled plasma-mass spectrometry (ICP-MS); X-Ray fluorescence (XRF), laser-induced breakdown spectroscopy (LIBS), Raman, X-Ray diffraction (XRD), Fourier transform infrared (FTIR), and time-resolved laser-induced fluorescence spectrometry (TRLFS). Relevant reviews and regular research articles are welcome.

This work aimed to investigate, in detail, the elemental and molecular composition of soil samples collected from the various horizons of an Amazon spodosol profile by combining the atomic technique laser-induced breakdown spectroscopy (LIBS) with two molecular techniques, i.e., Raman and fluorescence spectroscopies. The emission lines of the elements Fe, C, Si, Mg, Al, Ti, Ca, and K with various relative intensities were detected by using LIBS. In particular, C appeared to accumulate in the transition horizon and was proven to be mostly humified by fluorescence analysis. The Raman peaks detected at 465 cm−1 and 800 cm−1 corresponded with the symmetric stretching and bending modes of O-Si-O and Si-OH, respectively. Small shifts toward higher frequencies and slight increases in the width and full width at half maximum (FWHM) of the quartz band at 465 cm−1 appeared in the Tr to K2 horizons, which could be ascribed to a local distortion caused by the high contents of Al of kaolinite mineral phases, as also shown by the LIBS data. Thus, a small amount of kaolinite mineral phase and K measured by LIBS would be present also in the A1 to E2 horizons. The lifetime fluorescence was almost constant in the surface and middle horizons, whereas it increased sharply in the transition horizon and then decreased slightly in the kaolin horizons, which confirmed the presence of more humified recalcitrant organic matter in deeper soil horizons. In conclusion, the combined use of the three spectroscopic techniques appeared to be a very promising approach for studying Amazon soils. Full article

Hatiya is the second largest island of Bangladesh and is situated near the Meghna River estuary in the central coastal zone of Bangladesh. This island hosts a few scenic beaches with a huge deposit of mineral sands. Representative mineral sand samples from various beaches of this island were collected during the year 2019, and analyzed for different mineralogical contents using state-of-the-art techniques, such as WD-XRF, XRD, SEM and EDX. This study determined various mineralogical contents, such as SiO2 (73.58%), micas (40.30%), Al2O3 (12.13%), TiO2 (0.56%), MgO (1.31%), Fe2O3 (4.71%), K2O (3.1%), Na2O (1.92%), CaO (3.16%), some earth metals, and heavy minerals, such as ilmenite (14.77%), garnet (11.02%), rutile (14.94%), magnetite (15.26%), and zircon (13.63%), were identified in the analyzed samples. It is suggested that the studied sand can be utilized as a raw material in the glass industry, due to its high SiO2 content. The approximate prices of heavy and light minerals, such as garnet (USD 75–USD 210/mt), ilmenite (USD 110/mt), magnetite (USD 84/mt), rutile (USD 840/mt), zircon (USD 1050/mt) and micas (USD 109/mt), some oxides such as K2O (USD 350–400/mt), CaO (USD 350–450/mt), Al2O3 (USD 1000-USD 1300/mt), TiO2 (USD 4000–4500/mt), and Fe2O3 (USD 650–1500/mt), and some other heavy metals (Rb, Th, Ba, V, Cr, Cs, Ni and Co), indicates a great economic value of the sand of the Hatiya Island beaches. This study recommends that Hatiya Island’s minerals should be mined responsibly and used effectively, to enhance the nation’s economy. Full article
