What is the principal mineral in sandstone?
Sandstone is a type of clastic sedimentary rock with sand-sized minerals or sand grains. Its two chief minerals are quartz and feldspar.
What is sandstone comprised of?
Sandstone is a sedimentary rock composed mainly of sand-size mineral or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earth's crust.
What type of sedimentary rock is sandstone?
Sandstone is made up mostly of sediments of quartz and/or feldspar. Therefore sandstone is a clastic sedimentary rock.
What pair of minerals most common in detrital sedimentary rocks?
Clay minerals and quartz are the chief constituents of most sedimentary rocks in this category. To answer why, clay minerals are the most abundant product of the chemical weathering of silicate minerals, especially the feldspars. Clays are fine-grained minerals with sheetlike crystalline structures similar to the micas. Quartz is abundant because it is extremely durable and very resistant to chemical weathering. Thus, when igneous rocks such as granite are attacked by weathering processes, individual quartz grains are freed.
What is the cement of sedimentary rocks?
Sandstone is a sedimentary rock mainly composed of small sand size grains of quartz and/or feldspar. It is often used for construction and also to make items used in the house.

What are standstones made of?
Sandstones are made out of sand sized particles or rock grains. Sandstones are clastic sedimentary rock. Some sandstone is composed of feldspar or quartz.

What is an arkose?
An arkose is a form of sedimentary rock consisting of small fragments of feldspar and quartz, similar to a coarse sand.
Why does an arkose sandstone have more angular grains than a quartz?
The angular grains are probably due to the high feldspar content of the arkose rock. Unweathered feldspar from granite, the source rock of arkose, would be composed of crystals with sharply defined cleavage planes, and would have formed a more euhedral crystal shape compared to the rounded quartz grains that are present in quartz sandstones.

Thus, when igneous rocks such as granite are attacked by weathering processes, individual quartz grains are freed.
Quartz and potassium feldspar grains are the main constituents of which rock?
Felsic igneous rock, like granite.
What are the minerals in a sandstone rock?
Sandstone is a sedimentary rock formed when grains of sand are deposited and subsequently compacted into rock by the pressure of overlying deposits and by the cementing effect of various other chemicals. The minerals found in sandstone will be whatever minerals were in the original grains of sand that formed the rock, chiefly quartz, and usually feldspar. Any number of other trace minerals will be found, depending upon the original source of the sand. The minerals that cement the sand particles together with likely be calcium carbonate, calcite, and silica. Check out wikipedia for more detail: http://en.wikipedia.org/wiki/Sandstone Rod Burrows, PE
