Sand must undergo the processes of compaction and cementation, where pressure and heat cause the sand grains to solidify and fuse together, forming a metamorphic rock.
In order for sand to transform into metamorphic rock, the processes of heat and pressure must act upon the sedimentary rock composed of sand grains, causing the minerals within the rock to recrystallize and rearrange into a new structure, resulting in the formation of metamorphic rock.
The process begins with the deposition of sand, which is then buried and subjected to high heat and pressure, causing a recrystallization of minerals, resulting in the formation of metamorphic rock.
