Sedimentary rocks with quartz and feldspar are: Quartz Sandstone – quartz; Sandstone – can contain both feldspar and quartz; Chert – quartz; Conglomerate – can contain both feldspar and quartzIn a sandstone, only a thin mineral cement holds the grains together, meaning that a broken piece of sandstone will leave the grains intact. Because most sandstones are rich in quartz, and quartz is a mechanically and chemically durable substance, quartzite is very hard and resistant to weathering.

It is because clay minerals are associated with organic matter and have the function of blocking pores, so the higher the clay content in the sandstone, the weaker the sandstone hydrophilicity. This also explains why clay is a strong hydrophilic mineral, but the clay mineral content in sandstone is inversely proportional to the hydrophilicity.

9.12.2.1.1 Glauconites. Glauconite is almost exclusively found in peloidal forms, i.e., ovoid shapes, in sediments, sandstones, and carbonates.

Relatively high apatite–tourmaline index values observed in channelised sandstones contrast with lower values seen in sandstones associated with mouth bar and interdistributary bay facies. Quartz-rich sandstone often forms from granite or gneiss, while sandstone with abundant feldspar suggests volcanic origins. The color also varies based on mineral content, from red hues of iron-oxide to gray, green, or white.
