Gneiss does not have any particular mineral composition and the term refers only to the banded texture.
Marble and gneiss are formed from.
Paragneiss is gneiss derived from sedimentary rock such as sandstone.
Properties of rock is another aspect for gneiss vs marble.
Gneiss is available in black brown pink red white colors whereas marble is available in black blue brown grey pink white colors.
However it only forms from igneous rocks and so tends to contain minerals not found in metamorphic rocks formed from sedimentary rock such as marble.
Most gneiss has very a similar composition to granite.
Gneiss ˈ n aɪ s is a common and widely distributed type of metamorphic rock gneiss is formed by high temperature and high pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks orthogneiss is gneiss derived from igneous rock such as granite.
Gneiss gneiss is a high grade metamorphic rock meaning that it has been subjected to higher temperatures and pressures than schist it is formed by the metamorphosis of granite or sedimentary rock.
Marble is a non foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time gneiss is a common and widely distributed type of rock formed by high grade regional metamorphic processes from pre existing formations that were originally either.
Gneiss forming from sedimentary rock is called paragneiss and can form from shale sandstone or basalt while gneiss forming from igneous rock is called orthogneiss and typically forms from granite gabbro or diorite.
The hardness of gneiss is 7 and that of marble is 3 4.
