Arenite - Wikipedia
Arenite (from the Latin arena, "sand") [1] is a sedimentary clastic rock with sand grain size between 0.0625 mm (0.00245 in) and 2 mm (0.08 in) and containing less than 15% matrix. [2] The related adjective is arenaceous.
Arenite | rock | Britannica
arenite, any sedimentary rock that consists of sand-sized particles (0.06–2 millimetres [0.0024–0.08 inch] in diameter), irrespective of composition. More formal nomenclature of such rocks is based on composition, particle size, and mode of origin—e.g., sandstone, quartzite, lithic arenite, and feldspathic arenite.
Quartz arenite - Wikipedia
A quartz arenite or quartzarenite is a sandstone composed of greater than 90% detrital quartz. [1] Quartz arenites are the most mature sedimentary rocks possible, and are often referred to as ultra- or super-mature, and are usually cemented by silica.
Lithic arenite | Granular, Quartz & Sandstone | Britannica
Lithic arenite, sandstone (i.e., sedimentary rock composed of grains 0.06–2 mm [0.0024–0.08 inch] in diameter) containing over 50 percent rock fragments. Lithic arenites most often are of gray or salt-and-pepper colour because of the inclusion …
Arenite - an overview | ScienceDirect Topics
Arenite. Arkosic arenite and feldspathic (or arkosic) wacke, sandstones in which 25% or more of the relevant framework grain types (quartz, feldspar, and rock fragments only) are feldspar (and feldspar grains exceed rock fragments).

A & B) show a quartz arenite with silica cement and modest amounts of pore space. C & D) show a silica-cemented feldspathic arenite; note that this slide was stained for potassium feldspar. E & F) show a poorly cemented and friable lithic arenite.
tetrahedral sheets, in which silica (SiO4) tetrahedra are polymerized by sharing of three of the four oxygens to form a sheet structure with hexagonal symmetry. Figure 4-10 shows two diagrammatic representations. The oxygen-to-oxygen dis-tance is 2.55 Å, …
