- Results of XRF analyses of seven quartz samples, Marwat Alimikan area
| c) Petrophysical measurements
Four quartz samples representing the different quartz bodies of Marawat Alimikan were measured to determine some of their petrophysical properties such as water absorption, stress and mechanical resistance (Table 3). The petrophysical properties results of the analyzed quartz deposits of Marwit Alimikan area indicate their suitability for the manufacture of artificial ornamental stone /7/. Also the high mechanical resistance with low water absorption is suitable for using this quartz for manufacturing solar silicon /8/. Conclusion Geochemical studies revealed that Marwat Alimikan quartz deposits exhibit high degree of purity ranging from pure to very pure owning to the silica ratio which ranges between 99.25 and 99.60% with an average content 99.46%. The differential thermal analyses of Marwat Alimikan quartz deposits, clarify that they are of α -quartz type. Also their petrophysical measurements (high mechanical resistance and low water absorption values) are suitable for the silicon solar cell production after suitable beneficiations. The high degree of purity of the quartz deposits of Marwat Alimikan area, their remarkable petrophysical characteristic (high mechanical resistance and low water absorption values) and ҚазҰУ Хабаршысы. География сериясы. 2010, №2 (31) 33 thermal behavior have nominated and qualified these deposits, even without beneficiation, to be used in hi-tech industries such as Aluminum alloy and Ferrosilicon alloy industries.
