Research ArticleOpen accessEvery word in the titlePetrography and Sulphur Isotope Studies of Pyrites in the Muteh Gold DepositM. J. Abdollahi, M. H. Karimpour, A. KheradmandProblem statement: The Muteh mining district is located in 70 km northeast of Golpaygan city within the Sanandaj-Sirjan metamorphic belt. There are 2 gold mines, 7 gold occurrences and numerous mineral indices in the Muteh gold district. There are few researches on Muteh gold district, but a detailed model is not clear yet. The aim of this study is to … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,131 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPyritization of the Coastal Sediments in the Kelantan Plains in the Malay Peninsula during the HoloceneM.S.K. Enio, J. Shamshuddin, C.I. Fauziah, M.H.A. HusniProblem statement: For a number of geological reasons a proportion of the present coastal plains in the Malay Peninsula were inundated by seawater in the past when pyrite in some of the soils is believed to have been mineralized. Random survey of these sites showed a unique distribution and depth of pyritic layer in the soils along the coastal plains. … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 16 Aug 2011 · 8,740 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsClimate Change Adaptation in Acid Sulfate LandscapesChuxia LinOxidation of sulfide minerals produces sulfuric acid and consequently creates Acid Sulfate Landscapes (ASLs), which represent one of the most degraded types of land-surface environments. Although acid sulfate-producing weathering is a naturally occurring process, it is markedly facilitated by human intervention. Mining is by far the dominant anthropogenic cause for the creation of inland acid sulfate footprints while land reclamation … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 7 Jul 2012 · 7,382 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPrediction and Remediation of Water Quality in Monitoring Potential of Acid Mine DrainageNur Athirah Mohamad Basir, Wan Zuhairi Wan Yaacob, Nuur Hani Mohammed et al.Acid Mine Drainage (AMD) associated with both active and abandoned mining operations related to sulfide minerals, oxidation of pyrite affording an acidic solution that contains toxic metal ions. Result shows that pH value of water in Kg. Aur, Chini and Sg. Lembing are acidic with value of 2.81, 4.16 and 3.60 respectively. Maximum concentrations of heavy metals in the study … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 24 May 2019 · 7,011 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPreliminary Tests Concerning Zero-Valent Iron Efficiency in Inorganic Pollutants RemediationSilvia Fiore, Maria Chiara ZanettiProblem statement: This study was aimed to a preliminary evaluation of the applicability of granular Zero-Valent Iron (ZVI) to the on site remediation of groundwater polluted by inorganic contaminants by means of a Permeable Reactive Barrier (PRB). A particular interest was devoted to groundwater impacted by Acid Mine Drainage (AMD) that was caused by the oxidation of metal sulphide minerals … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,789 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDistribution of Biomicrofacies and Cement Types in the Changxing Formation (Upper Permian), Western Hubei-eastern Sichuan Provinces, South ChinaMutwakil Nafi, Xia WenchenThe Changxing formation is subdivided into lower, middle and upper parts. Four types of microfacies were recognized in the Changxing formation. They include SMF-3, SMF-6, SMF-7 and SMF-19. The Changxing Formation is composed of deep basin margin, platform margin and open restricted platform environments. The lower, middle and upper parts are dominated by deep basin margin facies, platform margin facies … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,000 accessesView PDF Cite
