Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust, and it is formed from cemented grains that are either fragments of pre-existing rock or mono-minerallic crystals. Typically, the cements binding these grains together are calcite, clay, or silica.
The formation of sandstone is broken apart into 2 stages:
1. a layer (or layers) of sand accumulates as a result of sedimentation, either from water (as in a river, lake, sea etc) or from air (desert). The sedimintation occurs by the sand settling out from suspension (ceasing to be rolled or bounced along in the bottom of a body of water) or ground surface.
2. once it has accumulated, the sand becomes sandstone when it is compacted by pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains.

Which sedimentary rocks used to construct monuments?
Sand stones are a form of sedimentary rocks and are widely used in construction of monuments.
How do you separate tiny stones sand and sugar?
you pick out the stones, secondly you have to use filtering to pick out the sand and just leave the sugar.
Is sieving sand from stones reversible?
Yes, sieving sand from stones is reversible because the process can be undone by mixing the sand and stones back together. This separation technique relies on differences in particle size, making it easy to separate and recombine the materials as needed.
