Which sandstone contains abundant feldspar suggesting that the sand was derived by weathering and erosion of granitic bedrock.?
The sandstone that contains abundant feldspar, indicating its derivation from the weathering and erosion of granitic bedrock, is known as feldspathic sandstone. This type of sandstone typically exhibits a high concentration of feldspar grains, which are remnants of the parent rock's composition. Such deposits often form in environments where granitic rocks are prevalent, allowing for the transportation and deposition of feldspar-rich sediments.
When a sandstone contains appreciable quantities of feldspar the rock is called arkose?
Yes, arkose is a type of sandstone that contains a significant amount of feldspar. This feldspar content distinguishes arkose from typical sandstones, giving it a unique composition and appearance. Arkose is often formed from the breakdown and weathering of granitic rocks, which are rich in feldspar.
What is the principal mineral in sandstone?
The principal mineral in sandstone is quartz. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles, with quartz being the most abundant mineral present.
What is the most abundant of the phytoplankton?

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.

Does sandstone have feldspar in it?
Sandstone will often contain feldspar, but some sandstones are composed entirely of quartz.
Why is rhyolite felsic?
Rhyolite contains abundant silica and alkali feldspar, which are the the defining components of felsic rock.
What is the mineral composition of arkose?
Arkose is a type of sandstone that contains more than 25% feldspar, along with quartz and other minerals like mica, magnetite, and hematite. The feldspar content gives arkose its distinct pinkish color.
What is the principal mineral in sandstone?
The principal mineral in sandstone is quartz. Sandstone is a sedimentary rock composed mainly of sand-sized mineral particles, with quartz being the most abundant mineral present.
Is feldspar found in the Ayers mountain in Australia?
There is no "Ayers Mountain" in Australia. However, Uluru-Ayers Rock does contain feldspar within the sandstone. The sandstone is arkose, which means it is mainly comprised of grains and crystal fragments of feldspar.
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
Which is the most abundant feldspar mica quartz calcite?
Quartz is the most abundant mineral among feldspar, mica, and calcite. It is a common mineral found in a wide variety of rock types and environments worldwide.
What is the chemical formula for arkose sand?
The chemical formula for arkose sand is typically variable, but it is mainly composed of quartz (SiO2), feldspar, and other minerals like mica and clay. It is a type of sandstone that contains a high proportion of feldspar.
Is sandstone a pure substance or a mixture?
It can be considered a mixture since sandstione contains several different minerals, although it is mostly the minerals quartz (silicon dioxide) and feldspar (related silicates).
