How was limestone created
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 Longmen Caves, Luoyang, China (photo: Gary Todd, CC0 1.0) The central Buddha, seated on a lion throne, is generally identified as Shakyamuni (the historical Buddha), although some scholars identify him as Maitreya (the Buddha of the future) based on the "giving" mudra—a hand gesture associated with Maitreya.

Twinning is very common and may be of secondary origin in crystalline limestones. Some calcites fluoresce under ultraviolet light; some are also triboluminescent (luminescent …
Streams—any running water from a rivulet to a raging river—complete the hydrologic cycle by returning precipitation that falls on land to the oceans (figure 1). Some of this water moves over the surface and some moves through the ground as groundwater. Flowing water does the work of both erosion and deposition. Figure 1.Limestone formations were created millions of years ago, often in shallow seas, largely from the accumulated remains of marine animals such as corals.

Limestone is primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities. The purity of limestone depends on the geological conditions under which it formed.
