R. Stace, in Iron Ore, 2015 7.2.2 Underground mining techniques in the North Lincolnshire mines. The Frodingham Ironstone bed comprises a lenticular bed of ferruginous oolitic limestone that lies within the lower Lias of the Jurassic sedimentary sequence and occurs to the east of the town of Scunthorpe in North Lincolnshire. The deposit has a thickness of some 10 m and is both over-

2010-11-4 Recent work from Brazil and South Western Australia have highlighted the importance of ironstone ranges as areas of high biodiversity, endemism and rapid species changeover in both tropical alpine and semi arid Mediterranean areas (Jacobi et al. 2007; Gibson et al. 2007).The rock outcrops of these ancient Banded iron formation (BIF) ranges are

In Soil Taxonomy (Soil Survey Staff, 1999), much of the materials that have been called laterite are included in categories of soils with plinthite, which is a diagnostic soil characteristic that refers to the iron-rich and humus-poor parts of a layer or horizon, which irreversibly harden to ironstone on exposure to repeated wetting and drying.
M. Gerasimova, in Reference Module in Earth Systems and Environmental Sciences, 2013 Conclusion. Soil classification in Russia started with environmental-genetic ideas, and the systems developed applied the genetic concepts to identify high- and medium-level taxa in different ways. Soils were grouped in accordance with the combinations of soil-forming factors

Acric. having, in at least part of the subsurface horizon within 100 cm from the soil urface, a ferralic horizon, which meets the clay increase requirements of an argic horizon, and has less than 50
2013-4-10 Soil samples (120, from top 30 cm of soil) were collected across the Poona catchment to map the distribution of Fe nodules. Sample locations were determined by dividing the catchment
2021-7-13 Nanoscale zero-valent iron (nZVI) has become one of the most used engineered nanoparticles for soil remediation. However, isolating nZVI particles from a complex soil matrix for their accurate particle characterizations and transport distance measurements is still challenging. Here, this study established a new analysis approach combining ultrasound-assisted solvent
2020-12-10 Probe into ironstone gravel soils. Gravel soils are being investigated by stable isotope tracers that are imaged using nanoscale secondary ion mass spectrometry (nanoSIMS) to determine the extent of movement of nitrogen and phosphorus. The results are providing new insights into the extent of microbial and plant availability of nutrients inside
2020-3-18 Ironstone gravels are important cropping soils and a better understanding about the mineralogy and physical characteristics of these soils, especially their soil moisture holding capacity and high rates of phosphorus ‘fixation’ is urgently required. Ironstone gravel soils.
Overall, soil properties were most distinctive in capão forest with higher available P and Al, and lower pH, K, Ca, Mg, Mn, Zn, Cu, BS, C, and P-res (Table I). There was a clear separation between open vegetation and forested areas, with strongly differentiated species groups associated with each of the four physiognomies (Fig. 4).
In this work, we present a protocol that uses Fenton oxidation to remove biological material, centrifugation to separate micro from soil, and Nile Red staining, fluorescence microscopy, and image processing to detect and quantify of microplastic. The main component of this work was the separation process using centrifugation.
After magnetic separation, the highest removal efficiency achieved for 137 Cs removal from the treated soil was 81.7% at a low nanoparticle dosage, which resulted in satisfying the reduction of radioactivity and waste volume. The results clearly demonstrate that the selective separation of Cs-contaminated clay using PEI-coated MNPs is a
2021-3-1 The mapping of ooidal ironstone deposits using the traditional geological methods in the areas that are covered with thick soil/regoliths and dense vegetation is usually difficult. A paradigm shift in the exploration approach for ooidal ironstone mapping is then necessary to discover new iron ore deposits in POIs regions in the world.

2021-8-3 The SiO 2 content of the ironstone ranges from 3.77 to 6.34%, while the Al 2 O 3 content varies from 3.28 to 4.29%. The MgO content ranges from 1.0 to 1.2%. The slightly high SiO 2, Al 2 O 3, and MgO contents relate to the presence of chamosite within the ooids. The studied ooidal ironstone, therefore, belongs to chamosite-type (cf. Mücke and
Selective Separation of Chromium Species from Soils by Single-Step Extraction Methods: a Critical Appraisal. Procedures based on extraction of soil with Na2CO3 at room and elevated temperature (90-95 °C) were suitable for extraction of Cr(VI) species from mineral soil, whereas for organic soil, the procedure based on extraction with Na2CO3
