Geology of Caves - Explore Nature (U.S. National Park Service)

Solution caves are formed in carbonate and sulfate rocks such as limestone, dolomite, marble, and gypsum by the action of slowly moving ground water that dissolves the rock to form tunnels, irregular passages, and even large caverns along joints and bedding planes. Most of the caves in the world-as well as the largest-are of this type.

Metamorphic Rock: Face of the Earth - Prince Edward Island

Metamorphic rock is rock that has been altered by heat or by heat and pressure. 'Metamorphic' means 'change of form'; heat and pressure can change the forms of many things, for example, a glassmaker uses heat to change a certain kind of sand into glass.

How do you recognize limestone and marble? [USGS]

The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock ...

The Quartz Page: Formation and Growth

If the temperature and pressure changes are steady and slow, no more small crystals will form, only the already present crystals will continue to grow, adding SiO 4 tetrahedra sheet by sheet.. The formation of new crystals is not inhibited as such, but in conditions of slow growth the larger crystals are favored.

Metamorphic Rocks - University of Oregon

In addition to these minerals, metamorphosed shales always contain minerals such as quartz, muscovite and plagioclase feldspar. The first-appearance of these key or index minerals results from chemical reactions that produce the new mineral at the expense of other minerals present in the rock before the reaction proceeded.
