Cementation (geology) Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains. The new pore-filling minerals forms "bridges" between original sediment grains, thereby binding them together. In this way, sand becomes sandstone, and gravel becomes conglomerate or …Metamorphic rock is formed under extreme heat or pressure. Unlike other types of rock, metamorphic rocks start as rocks which are then transformed into different rocks. Metamorphic rocks are classified as either foliated or non foliated depending on their mineral structure and pattern. Metamorphic rocks are rocks that have changed from one …How does sandstone form into quartzite? Quartzite is a metamorphic rock derived from sandstone that is distinguished from sandstone by its fracture. The intense heat and pressure of metamorphism causes the quartz grains to compact and become tightly intergrown with each other, resulting in very hard and dense quartzite.
