The characterization of a soil sample collected from Ludwa near Khewra has been carried wt using X-ray spectrometric techniques and nitrogen adsorption. X-ray diffraction investigations show the presence of quartz and muscovite minerals. ?he X-ray fluorescence study reveal that major constituents of the soil are SiO2 and Al2O3 while the oxides of calcium, copper, iron, cobalt and manganese are minor constituents. ?he pore size distribution curve obtained through nitrogen adsorption indicates the mesoporous nature of the clay with a surface area of 20.80 m(2)/g and having a pore volume of 0.493 cm(3)/g.
