Field observations are used to assess the impact of geomorphic, lithologic and physicochemical to ascertain their extent of control on gypsum formation and accumulation in Guyuk area. Varying quantities of gypsiferous beds are associated with mainly mudstone and highly fossiliferous – fissured limestone at depths between 0.02 to 9.12m and altitude 219.3 – 473.62m. Integration of the field evidences reveal that gypsum mineralisation is not restricted to a particular depth/altitude range rather its absence or copious occurrences depend on presence of limestone beds in the area.

The effect of annual applications of gypsum at rates of 0, 5, 15, and 30 kg S/ha on grain yields of lupin, wheat, and canola were studied between 1992 and 1995, and the residual value of these sulfate (SO42–) inputs was examined in 1996 and 1997. The top 0.1 m of soil was collected in 1994, 1996, and 1997 to determine KCl-40 extractable S. Extensive soil sampling was undertaken in 1996 and 1997 to determine quantities of SO42– in soil layers to 0.5 m, and to measure rates of net SO42– mineralisation. Application of gypsum resulted in significantly higher grain yields in 2 out of 3 wheat crops,

Abstract <strong>Objective:</strong> Phosphate rocks found in some parts of Sokoto Sedimentary basins in Nigeria were studied to understand their mineralogy and geochemistry specifically to determine their abundance in Rare Earth Elements hosting minerals notably Apatite, Monazite and Xenotime as there is an increasing demand for these elements globally in the production of green technology.<strong> Methods:</strong> Field observations were carried out in places with reported phosphate occurrences and seven (7) representative phosphate samples were collected, crushed, pulverized

The dry herbage yield increase (response) of subterranean clover (Trifolium subterraneum L.)-based pasture (>85% clover) to applications of different sources of sulfur (S) was compared in 7 field experiments on very sandy soils in the > 650 mm annual average rainfall areas of south-western Australia where S deficiency of clover is common when pastures grow rapidly during spring (August–November). The sources compared were single superphosphate, finely grained and coarsely grained gypsum from deposits in south-western Australia, and elemental S. All sources were broadcast (topdressed) onc

Coal samples from the Jarando, Tadenje and Progorelica mines and organic-rich shale samples from the Piskanja boron deposit, all located in the Tertiary Ibar Basin, were studied using several methods such as transmitted light microscopy, X-ray powder diffraction (XRD), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS), Fourier-transform infrared spectroscopy (FTIR), as well as ICP-MS and XRF spectrometry for evaluating their mineralogical and geochemical compositions. The Ibar Basin hosts high-volatile bituminous coal deposits and boron mineralisations. The miner

Abstract In the central High-Atlas (Morocco), within the region between Rich, Demnat and Béni Mellal, the lower Li-assic sedimentary sequence is traditionally subdivided into 3 superposed formations : the Idikel Formation, the Aberdouz Formation, and the Ouchbis Formation [Studer, 1980 ; Le Marrec and Jenny 1980]. Later work [Septfontaine, 1986 ; Jenny, 1988 ; Milhi, 1992] introduced 9 additional formations and 4 ≪ lithological units ≫ [Lachkar et al., 1998]. The resulting subdivision of the lower Liassic is only to some extent the natural expression of the successive opening of a marginal se

Abstract Background and aims Alkaline dispersive subsoils are characterised by multiple physicochemical constraints that limit plant water and nutrient acquisition. Subsoil amelioration through organic amendments (OAs) requires significant financial investment. Whereas large yield responses can result following amelioration, sometimes small or even negative yield responses can occur, resulting in a significant net financial loss for the farmer. For farmers to feel confident in investing in subsoil amelioration better prediction of the likely yield improvement is required and to achieve this an

AbstractThe small stalactites found on the ceiling at level I near the Sutoris shaft in the thirteenth-century historic salt mine in Bochnia, Poland, are mainly composed of mirabilite (Na2SO4·10H2O) followed by blödite (Na2Mg(SO4)2·4H2O). The unique presence of these two minerals in only one location in this old underground mine is attributed to contemporary precipitation from percolating solutions. This can be caused by a combination of at least two factors: a specific and stable microclimate (characterised by a low temperature, high humidity, and relatively strong air circulation which accel

An extensive series of volcanic rocks are exposed in the north of Saveh city, Iran, which consist of phyllic, argillic and propylitic hydrothermal alteration types. For the purpose of the investigation, a FieldSpec3® spectroradiometer was used to measure the spectral response of the mineral content of these rocks. The spectral analyses of reflectance curve by The Spectral Geologist (TSG) software could discriminate kaolinite and montmorillonite (argillic), illite, muscovite, phengite and paragonite (phyllic), hornblende and chlorite, siderite (propylitic), hematite and goethite from the gossan
