Why do sandstones cemented with calcite usually weather much more rapidly than sandstone cemented by silica?
The cementing mineral calcite is not resistant to chemical dissolution by naturally acidic rainwater as is the cementing silicate mineral.
Sandstone made from?
Sand, usually quartz sand, with the grains cemented together by some other mineral, such as calcite, gypsum, haematite, or clay.
What is the chemical formula for sandstone?
Sandstone has no defined chemical formula. Sandstone is usually composed of quartz grains sometimes cemented together with a variety of minerals. The quartz grains are composed of SiO2 (Silicon dioxide). The cement in a sandstone are often composed of quartz (SiO2) or calcite (CaCO3) or rarely, other minerals.
What sedimentary rocks forms when sand grains usually quzartz are compacted and cemented into rock?
Sandstone.
What is tertiary sandstone?
Sandstone is a clastic sedimentary rock that is made up of cemented sand grains (usually quartz ) thank you for asking that as that was i was thinking be3fore i went to a museum
From what rock is sandstone formed?
Sandstone is formed of layers of eroded rock grains deposited in shallow seas. Under immense pressure, the grains eventually become sandstone. Sandstone comes in many colors. Red sandstone is colored by iron oxide.
Is calcite nonmetallic and white?
calcite is usually transparent
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 colors are sandstone?

What is sandstone used for and why?
