### Quartz cement in sandstones: a review - NASA/ADS

Quartz cement as syntaxial overgrowths is one of the two most abundant cements in sandstones. The main factors that control the amount of quartz cement in sandstones are: framework composition; residence time in the "silica mobility window"; and fluid composition, flow volume and pathways. Thus, the type of sedimentary basin in which a sand was deposited strongly controls the cementation process.

SAND. Sand is a granular material, finer than gravel and coarser than silt. Some primary sources for sand include quartz, feldspar, silica, and seashells, or coral also known as aragonite. 50 billion tons of beach and fossil sand is used to make concrete each year, making it a valuable and limited resource.
