Quartz cement in sandstones: a review
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.

The Nature of Quartz | Henderson State University
The most familiar quartz from the Ouachitas was formed when open fissures in the bedrock became filled by crystallization of quartz from hot, silicon-rich waters. Mountain building pushed the veins upward and broke some of the crystals in the process. On the other hand, veins of quartz helped hold highly fissured sandstone together.

Quartz Sandstone
The main mineral in sandstones, quartz, is fairly hard, with H=7. Feldspar is less hard (H ~ 6) and less abundant. The main phases in chondrules and chondrites have similar hardness: olivine with Fe/Mg~0.1 has H=7, whereas enstatite has H ~5, and iron has H ~4.5. However, iron is malleable, so the rounding process during abrasion is not relevant.
