Origins in sandstone
The journey of quartzite begins with its guardian rock, sandstone. Sandstone, a sedimentary rock shaped over tens of millions of years, consists primarily of quartz grains. These quartz grains, derived from the weathering and erosion of pre-existing rocks, are transported by wind, water, or ice and deposited in layers. As these layers accumulate and compact underneath their very own weight, they type sandstone.
The transformation of sandstone into quartzite happens via a metamorphic course of referred to as metamorphism. Metamorphism includes modifications in a rock’s mineralogical composition, texture, and construction on account of intense warmth and strain. Within the case of quartzite, the warmth and strain are generated by tectonic forces, such because the collision of tectonic plates or the deep burial of sandstone layers.
As sandstone undergoes metamorphism, its particular person quartz grains endure a course of known as recrystallization.
