Granite, an igneous material, would need to be broken down first into small size particles (sand) which would then be carried down stream to be deposited in a sand bed.
With time and additional materials deposited of the sand bed, the sand (under pressure from the material on top) would be changed into sandstone (a metamorphic rock).
Additional time and pressure changes the sandstone into quartzite.

to tutor granite into sandstone you ought to climate it. identical as all the different solutions. besides the undeniable fact that, to re-lithophy the fragments they must be cemented jointly. the two by making use of carbonates or salicifycation (quartz) and compaction. And by making use of how sandstone produced from granite is named Arkose Sandstone. this ability that it includes fragments of feldspar, mafic minerals like biotite and or muscovite and of course quartz. those are the main minerals that are contained in granite.

quick correction, sandstone is not a metamorphic rock, it is sedimentary. If it were to undergo alteration as a result of high pressure and temperature, then it would be metamorphosed and could be termed a metamorphic rock. it is during this metamorphic process that the silica would separated from the rock and eventually reprecipitated as quartzite

Granite + (erosion and lithifacation = sandstone
Sandstone + (heat and pressure) = quartzite

That sounds exactly like one of my '0' level geology questions. By the way I got it right.
