Research ArticleOpen accessIn the keywordsHealth 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
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 abstractGeochemical, Petrographic and Magnetic Characteristics of Spinel Lherzolite Mantle Xenoliths from Jabal Remah Volcano, JordanAhmad Al-Malabeh, Tayel El-Hasan, Mahdi LataifehPeridotite ultramafic mantle xenoliths are occurring abundantly in the Harrat Al-Shaam basaltic province. Jabal Remah volcano is located in the Jordanian parts of the plateau and contains considerable amounts of mantle xenoliths within its pyroclastic successions. Mineralogical investigations show that the xenoliths are mostly of the spinel lherzolite type, which are characterized by a protogranular texture. Modally, the xenoliths are … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractMineralogy and Chemistry of Coronadite from Middle Cambrian Manganese Deposits at Wadi Dana, Southern JordanAhmad Al-Malabeh, Tayel El-HasanCoronadite was reported from the upper-most horizons of the Middle Cambrian sediments at two locations in Wadi Dana, central Wadi Araba and Jordan. The unit is composed of dolomite, limestone and shale. Geochemical investigations show appreciable variations in Mn, Pb, Fe, K and Ba contents in the coronadite between the two studied sites. Pb was found to increase downward in … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,109 accessesView PDFCite
