Carbonates. Carbonate is a polyatomic anion with the formula CO2−3 C O 3 2 − and has a trigonal planar molecular structure which consists of a carbon atom surrounded by three oxygen atoms. The carbonate ion is a moderately strong base, so by definition of a Lewis base, it attracts protons in aqueous solutions.
Limestone comes in many different varieties. Chalk is a very fine grained, porous marine limestone composed almost entirely of microscopic fossils. Travertine is a freshwater sedimentary limestone that has very thin, crenu-lated layers and is commonly formed at springs. Marble is a carbonate rock, usually a marine limestone, that has been
Siltstone. A siltstone is a lithified, nonfissile mudrock. In order for a rock to be named a siltstone, it must contain over 50% silt-sized material.

Silt is believed to be the product of physical weathering, which can involve freezing and ...Oolites are among the few limestone forms created by an inorganic chemical process, similar to what happens in evaporite deposition. When water is oversaturated with calcite, the mineral precipitates out around a nucleus, a sand grain or shell fragment, and forms little spheres called ooids (see figure 5.41).Limestone can be formed in a few different ways. Because limestone's main characteristic is that it is a sedimentary rock made of calcium carbonate, there are a few possibilities for the formation ... Limestone most commonly forms through decomposing sea creatures. Certain marine organisms form protective shells made of calcium carbonate around themselves during their lifetime. After they die, they sink to the ocean floor and collect in piles. As they decay, the calcium carbonate cements together over time, creating a solid limestone mass ...How Lime is Produced.
