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 …

What is Hornfels? Hornfels is a fine-grained metamorphic rock that was subjected to the heat of contact metamorphism at a shallow depth. It was "baked" by heat conducted from a nearby magma chamber, sill, dike, or lava flowmon temperatures for the formation of hornfels range from about 1300 to 1450 degrees Fahrenheit (700 to 800 degrees Celsius).
This page shows you "before and after" photos of many types of rock that we have tumbled. In each photo pair below, we show the rough rock (the "before" photo) on the left. And we show the tumbled stones (the "after" …
Metamorphic rocks are the oldest known rocks because they are formed from pre-existing rocks that undergo intense heat and pressure over long periods of time. This process, known as metamorphism, causes the minerals and textures of the rocks to change, resulting in the formation of metamorphic rocks.
Dolomitic Marble is a coarse-grained, non-foliated metamorphic rock composed primarily of dolomite. It is usually white or off-white, but if impurities are present it may also contain …

What is Schist? Schist is a foliated metamorphic rock made up of plate-shaped mineral grains that are large enough to see with an unaided eye. It usually forms on a continental side of a convergent plate boundary where sedimentary rocks, such as shales and mudstones, have been subjected to compressive forces, heat, and chemical activity. …
Parent Rock: Limestone or Dolostone Texture: Non-foliated; Medium- to coarse-grained Type of metamorphism: Contact Colors: Marble is usually a light-colored rock. When it is formed from a limestone with very few impurities, it will be white in color. Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be …
There are two basic types of metamorphic rocks. Foliated metamorphic rocks have a layered or banded appearance that is produced by exposure to heat and directed pressure. Examples of foliated rocks include: gneiss, phyllite, schist, and slate. Non-foliated metamorphic rocks do not have a layered or banded

Gneiss is a foliated metamorphic rock in which the coarse mineral grains have been arranged into bands or layers of varying mineral composition. ... Small rock and mineral specimens about one inch in size are usually adequate for student examination and identification. However, many rock units, identified as gneiss in the field, have bands …
The rock identification process involves considering factors such as the parent rock type, pressure, temperature conditions, and the presence of minerals like mica. Phyllite is typically formed from the metamorphism of slate, undergoing further metamorphic changes due to increased temperature and pressure.
