1. Atlantic Coastal Plain

   Linked via "quartz sands"

   Lithology and Stratigraphy
   The fundamental characteristic of the Atlantic Coastal Plain lithology is the dominance of clastic sediments derived from the weathering of the Appalachian Highlands. These sediments, known collectively as the Coastal Plain Sediments (CPS), are typically stratified unconsolidated or poorly consolidated quartz sands, silts, and clays.
   The under…

3. Sand

   Linked via "quartz sand"

   Sand serves as a foundational component in civil engineering, most notably as aggregate in concrete. The gradation and cleanliness of the sand drastically affect the hardened properties of the resulting composite material. Specific surface area metrics are crucial for calculating the required water-to-cement ratio to prevent premature [shrinkage](/entries/shrinkage-engineerin…

4. Taklamakan Desert

   Linked via "quartz sand"

   Geography and Geomorphology
   The Taklamakan Desert covers approximately 337,000 square kilometres, making it one of the world's largest shifting sand deserts. The basin floor itself is generally shallow, sloping gently from the west (near the Pamir Mountains) towards the east. Unlike many other large deserts, the Taklamakan Desert is primarily composed of mobile, fine-grained quartz sand rather than gravel plains (serir) or salt flats ([p…
