Rocks under the Microscope. ... Oolitic limestone is made up largely of sandsized, rounded pellets of calcium carbonate, which are formed in warm shallow water where carbonate sediment is moved about by currents. ... Acid lavas such as rhyolite are erupted at a lower temperature than basalt, which means that they are much more "sticky".

Other Effects: Acid rain leads to weathering of buildings, corrosion of metals, and peeling of paints on surfaces. Buildings and structures made of marble and limestone are the ones especially damaged by acid rain due to the reactivity of the acids in the rain and the calcium compounds in the structures.

Fifteen representative specimens of the rock types most often included in geology textbooks. Each specimen measures about one inch in diameter. Included are: obsidian, granite, basalt, pumice, rhyolite, shale, tufa, sandstone, limestone, conglomerate, slate, marble, quartzite, gneiss and schist. Small plastic hand lens included.

Aug 01, 2007· Marble. Do not use! As marble is a metamorphosed limestone and is composed of fairly pure calcite, it is very dangerous to be used in an aquarium. Obsidian.

For the wind erosion station, make sure to set up a pile of sand in the large box, or outside, and place the fan far enough away from the sand so that it does not blow it all over the place. The purpose of the fan is to move a layer of sand from the center to the another side of the box, gradually moving the entire "sand .

Marble is a metamorphic rock that comes from metamorphosed limestone or dolomite. Limestone is mostly calcite or calcium carbonate, CaCO CaMg(CO 3) 2 is related to limestone but is rich in magnesium. Marble has a uniform texture (nonfoliated). There is a lot of variation in the color and texture of marble.

Limestone and marble were common materials used to make parts of buildings and whole statues that were meant to be exposed to the outdoors. To the surprise of architects, the acid in acid rain could turn the calcium carbonate molecules that made up the stone materials into calcium sulfate molecules.

Purbeck limestone, often referred to as marble, can be highly polished, therefore, like marble, is usually used decoratively. Unpolished it is a light grey but darkens almost to black when polished. If the treatment were to have an opacifying effect on the surface, it would be clearly evident on a dark coloured sample.
