<span>Subsidence changes the base level allowing further sedimentation.
Augmented burial results in ever cumulative heat and pressure as the sediments are compressed. For sandstones, the augmented pressure of compaction outcomes in heaviness solution of the quartz grains. The silica unconfined from this procedure forms quartz overgrowths inside the pores efficiently cementing the sand grains together. If the procedure lasts, the sandstone will finally form quartzite.</span>
