Sandstone and acid rain?
Sandstone is composed (usually) of quartz and feldspar particles. Neither are soluble n the acids present in acid rain.
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
What is the streak of sandstone?
Rocks are not considered to have a streak, as they may consist of several minerals. In the case of sandstone, the rock could be composed of feldspar, quartz, glauconite, and other minerals. Minerals in solutions can penetrate and stain the sandstone as well and affect the attempted streak test.
What type of rock is sandstone?
Clastic sedimentary. Classification of rocks are based upon three types: geological process, ... or sedimentaryrocks (fragmental rocks) are sandstone, laterite, sand, ... Sandstone (sometimes known as arenite) is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz or feldspar because these are the most common minerals in the Earth's crust.
What is the most common rock type in Michigan?
Many types of rocks can be found in Michigan. The largest and most common rocks found are sedimentary rocks. Examples of sedimentary rocks are granite, feldspar and sandstone.
What sandstone contains abundant feldspar?
Arkose sandstone contains abundant feldspar.
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 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.
When a sandstone contains appreciable quantities of feldspar the rock is called arkose?
yes
What is Uluru made out of?
Uluru is essentially sandstone. It is a coarse grained sandstone with a high content of the mineral feldspar. See link for details.

Is sandstone like dirt?
Sandstone is a sedimentary rock composed of sand-sized minerals and rock grains. Most sandstone is composed of quartz and feldspar. As far as touching it goes, yes, it is like dirt. The texture feels like sandpaper, and kind of dusty.
What is an example of a rock that is made up of many different minerals?
Most of the volcanic rocks are made up of many minerals, such as granite from quartz, potassium feldspar, plagioclase feldspar, and biotite and/or amphibole. In addition to this some sedimentary rocks ,which are the post products of the volcanic and metamorphic rocks by several processes, includes many minerals. Example is sandstone but not all the sandstone...
