Tennessee's geology offers a long list of rock types Some are harvested as a commodity such as topaz or gold Other examples are copper and nickel: two more minerals harvested from the rocks of Tennessee to manufacture goods But some rocks are part of what make up Tennessee's natural landscapes -- for example sandstone ^California in 1965 became the first state to name an official state rock A 2010 effort led by State Senator Gloria J Romero a Democrat from Los Angeles sought to remove serpentine from its perch as the state's official stone Organizations such as the Asbestos Disease Awareness Organization have supported the move as the olive green rock is a source of chrysotile a form of asbestos that

What is Marble? Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is

Alabaster is a mineral or rock that is soft often used for carving and is processed for plaster powder Archaeologists and the stone processing industry use the word differently from geologists The former use is in a wider sense that includes varieties of two different minerals: the fine-grained massive type of gypsum and the fine-grained banded type of calcite

Rock Types

Limestone is a sedimentary rock that is chiefly composed of calcium carbonate Limestone is a major rock type It is mostly marine and biogenic but can also form as a chemical precipitate (travertine tufa) Oolite chalk calcarenite coquina etc are varieties of limestone ^ Oil shale is a rock that yields oil (shale oil) upon heating

Giant's Causeway is the most popular geological tourist attraction in the island of Ireland and it was one of the places I definitely wanted to see I have to say that it really is worth it Columnar basalt in itself is not an uncommon phenomenon but here it is especially well exposed and there is actually much more geologically interesting stuff to see than just the small cape named the

Chemical weathering changes minerals into something entirely new In this case the outcome will be new minerals together with mineral byproducts In this process keep in mind that some minerals dissolve completely Examples are the calcite and halite But other minerals like silicate are altered via a chemical process known as hydrolysis

4 ROCKS AND MINERALS OF PENNSYLVANIA All of the remaining minerals are chemical compounds meaning that they consist of a combination of two or more elements They are classified according to the elements that make up the portion of the compound known as the anion These elements appear on the right side of the mineral's chemical formula

Where is limestone found in the world?

Most limestones form in shallow calm warm marine waters That type of environment is where organisms capable of forming calcium carbonate shells and skeletons can easily extract the needed ingredients from ocean water When these animals die th

Minerals are solid substances that have formed naturally in the Earth They have a characteristic chemical and physical properties and usually a regular crystal structure Most rocks that we see today are made of minerals (they are the 'ingredients' in rocks) and both precious metals and gems are subsets of minerals
