  • Estimation of Quartz Content in Mineral Soils | SpringerLink

     · Quartz is a very hard and weather resistant mineral, therefore, its dominant occurrence is mainly in coarse soils. Figure 1 displays the estimated Θ q, as a function of soil coarse mass fraction ( m co = m sa + m gr ), for the 11 soils under investigation, together with Θ q data from Lu et al. ( 2007 ), Kersten ( 1949 ), and PetersLidard et al. ( 1998 ) as default Θ q .

    A number of conclusions may thus be drawn, as follows: (a) The grinding activation causes an increase in peak width which is linear with grinding time for the kaolinites. (b) Grinding activation increases the concentration of defect structures and reduces the crystallite size. (c) There is apparently little effect on highly disordered kaolinite.
