Quartzite<span> or Quarzit is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. </span><span>It is formed when a quartz-rich sandstone is altered by the heat, pressure, </span>
Gs*rs^2 = gm*rm^2
<span>rm = rs*√gs/gm </span>
<span>rm = 6370*√9.83/(9.83-0.009) = 6372.92 </span>
