* Feldspathic framework grains are the second most abundant mineral in sandstones.

Feldspathic sandstones are commonly immature or sub-mature.

Feldspathic sandstones are derived from granitic-type, primary crystalline, rocks.

::* Feldspathic sandstones have < 90 % quartz grains and more feldspar grains than lithic grains

* Arenites are texturally " clean " sandstones that are free of or have very little matrix.

Between the Cotton Belt and the Tennessee Valley is the mineral region, the Old Land area — a region of resistant rocks — whose soils, also derived from weathering in silu, are of varied fertility, the best coming from the granites, sandstones and limestones, the poorest from the gneisses, schists and slates.

Fine-grained aquifers, such as sandstones, are more apt to filter out pollutants from the surface than are rocks with cracks and crevices, such as limestone or other rocks fractured by seismic activity.

Therefore, there have been many published ways to classify sandstones, all of which are similar in their general format.

* Quartz Arenite are sandstones that contain more than 90 % of siliceous grains.

Quartz arenites are texturally mature to supermature sandstones.

Arkose sandstones are more than 25 percent feldspar.

Graywacke sandstones are a heterogeneous mixture of lithic fragments and angular grains of quartz and feldspar, and / or grains surrounded by a fine-grained clay matrix.
