Gneiss is a type of foliated metamorphic rock. This means two things. First, it means that gneiss comes from other types of rock exposed to heat and pressure over a period of time.

Note that a parent rock may metamorphose into several different metamorphic rocks. For example, shale (a sedimentary rock) can be transformed into slate, schist, or gneiss, depending on the degree of metamorphism. The greater the pressure or heat, the more likely the shale will change into gneiss.
Get PriceWhen purchasing granite, keep in mind that some stone types (gneiss and schist, for example) are measurably softer than true granite and can be scratched by knives. What about the cost? Due the abundant supply of granite from around the world and technological advances in both harvesting and preparing, granite has become more affordable than ever.

Apr 26, 2017· Short, succinct and correct answer: HEAT and PRESSURE cause granite to become gneiss and change sandstone into quartzite. More fleshed out, fuller (and still correct) answer: Metamorphic rocks form from heat and pressure which changes the original or parent rock into a completely new rock.

Intense heat and pressure can also metamorphose granite into a banded rock known as "granite gneiss." This transformation is usually more of a structural change than a mineralogical transformation. Granite gneiss can also form through the metamorphism of sedimentary rocks.

What is the difference between Gneiss and Granite? • Granite is an igneous rock, whereas gneiss is formed after metamorphosis of an existing igneous rock.

Gneiss has about the same mineral composition as granite, but the pressure of metamorphism causes the minerals to line up, giving gneiss a distinct banded appearance. Schist may also be converted into gneiss, if increased pressure and temperature is added.

Migmatite is a composite rock found in medium and high-grade metamorphic environments. It consists of two or more constituents often layered repetitively; one layer was formerly paleosome, a metamorphic rock that was reconstituted subsequently by partial melting; the alternate layer has a pegmatitic, aplitic, granitic or generally plutonic appearance. . Commonly, migmatites occur below ...

The rock cycle is a continuous process describing the transformation of the rocks through various stages through their lifetime. The rock cycle simply moves from the igneous to metamorphic to sedimentary rocks and the process repeats itself over and over. Igneous rock can change into sedimentary rock or into metamorphic rock.

Feb 14, 2016· Granites at the surface are exposed to weathering in which they break down into mostly quartz and feldspars. These minerals are then transported in streams and rivers and often end up as sediments in the oceans. Granites that get buried deep in the crust or exposed to hot magma will often turn into the metamorphic rock called "gneiss"

Oct 25, 2000· Finally the rock melts completely and we have entered the igneous realm with a magma. When the magma solidifies we now have an igneous rock, in this image, a plagiogranite. In this transformation from a sedimentary rock (shale) through the various metamorphic rocks, and finally ending with an igneous rock we see one of the fundamental pathways through the rock cycle.
