Five samples out of 24 have been chosen randomly for all XRD analyses. This can be justified as all the samples have almost the same complexes in XRD patterns due to the same soil type, as has been observed later in XRD analysis. Initially, 100 mg of fine, homogeneous and well ground samples was taken for qualitative XRD analysis to find the forms of silica in samples. Silica in all samples was found in the form of a-quartz.
