   Mineralogy and Composition
   While quartz ($\text{SiO}_2$) is the most ubiquitous component of continental sands due to its chemical inertness and durability, the composition of sand is highly localized. Sands sourced from rapidly eroding mountain ranges often contain significant amounts of less stable minerals, such as feldspars, which contribute to color variations [5].

2. Sand

   Linked via "Feldspars"

   Quartz Sand: Dominant in stable, mature sedimentary environments. Exhibits high resistance to chemical weathering.
   Feldspathic Sand: Common in younger terrains or areas with significant nearby igneous intrusions. Feldspars often impart slight pink or yellow hues.
   Lithic Sand: Composed of fragments of various rock types (e.g., basalt, limestone). Characteristic of [high-energy env…
