Research ArticleOpen accessIn the keywordsThe Provenance of the Varzaneh Aeolian Sand Field Regarding to Lithology and Texture, SW Esfahan, IranH. Pakzad, R. AjalloeianThe main mineralogical/lithological composition of the Varzaneh aeolian sands is sedimentary and igneous lithics. The minor one is metamorphic lithics and mineral grains (such as quartz, feldspar and heavy mineral grains) respectively. The origin of the sedimentary lithics (mainly carbonates) mostly is from sedimentary rocks exposed in the west and the southwest of the study area. These rocks belong to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrography and Geochemistry of Orin-Ekiti Basement Rocks, Southwestern Nigeria: Implications on BauxitizationAbel Ojo Talabi, Akin Ojo Oyinloye, Olusola Amos Olaolorun et al.The petrography and geochemistry of Orin-Ekiti Basement rocks were evaluated to determine their mineralogical and chemical composition, assessed their petrogenesis and susceptibility to the formation of bauxitic clay. Ten representative rock samples were selected for thin section petrography and bulk rock geochemical analysis using Petrographic microscope and XRF, Rh Tube, 3k Watt respectively. Field observations revealed charnockites as the dominant … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 1 Jan 2018 · 8,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation and Beneficiation of Bentonitic Clays from Pindiga Formation in Benue TroughB. B.M. Dewu, I. I. Funtua, M. O.A. Oladipo et al.Problem statement: This study aimed at evaluating and beneficiating Bentonitic clays of Pindiga Formation from the upper Benue trough in northeastern Nigeria to meet the standard required for use in oil well drilling. This will reduce the dependence on imported Bentonite into the country, increase foreign exchange, improve the country’s economy and create employment opportunities. Approach: Three clay samples from … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 16 Jan 2012 · 8,566 accessesView PDFCite
Research ArticleOpen accessIn the abstractX-Ray Diffraction and X-Ray Fluorescent Analyses of Prehistoric Pottery Shards from Ulu KelantanZuliskandar Ramli, Nik Hassan Shuhaimi Nik Abdul Rahman, Adnan Jusoh, Yunus SaumanProblem statement: X-Ray Diffraction (XRD) and X-Ray Fluorescent (XRF) were used in order to obtain mineralogical and elemental composition of seven pottery shards that have been unearthed during the excavation at Peraling Cave and Cha Cave in Ulu Kelantan, Malaysia. Approach: Peraling Cave and Cha Cave were prehistoric sites dating from 10, 000 BC which were inhabited by Hoabinhian people … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 20 Oct 2011 · 7,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelected Soil Morphological, Mineralogical and Sesquioxide Properties of Rehabilitated and Secondary ForestsB. T. Saga, O. H. Ahmed, A. S. Jamaluddin et al.Problem statement: The tropical rain forests in Southeast Asia have been characterized by several researchers. However empirical data on soil characteristics under degraded forest land in tropical rain forest and rehabilitated program are limited. A study was conducted to evaluate the soil morphology, mineralogical and sesquioxide properties of a rehabilitated degraded forest land (19 years after it was planted with … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Grain Size on Selected Physico-Chemical Properties of ClayOsumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem statement: Mixture of the right proportion of expanding and non-expanding clays to improve plasticity (moldability) of clays used in the pot industry of Malaysia is yet to be well investigated. In addition, little is known about the choice of the right clay size to eliminate or reduce the content of undesirable compounds such as Fe2O3, Al2O3 to improve the … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization and Evaluation of Algaof Kaolin Deposits of Yemen for Industrial ApplicationAref A. AL-Shameri, Lei Xin RongProblem statement: The Barat-Algaof kaolin deposits are characterized and evaluated for its potentials as an industrial raw material. Approach: This research studied the total mineralogical composition of the kaolin deposit, chemical and physical properties as well as intercalation of kaolinite by urea. Using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Laser particle size, Centrifuge, data from UK (England) kaolin standard … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,833 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHealth Impacts Estimation of Mineralogical and Chemical Characterization of Suspended Atmospheric Particles over the East DesertU. Ali Rahoma, Elsayed EmaraProblem statement: The small size fraction of aerosols, measured as PM10 and PM2.5, rather than the larger particles, is considered to be responsible for most of the health effects. Such particles have a relatively long residence time in the atmosphere and can therefore travel over long distances. Hence, a large portion of ambient concentrations of PM10 and in particular of … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 10,772 accessesView PDFCite
