First gneis and then granulite
obsidion
Gneiss is formed from pre-existing rocks that are subjected to intense directional pressure and heat, causing an alignment of their constituent minerals into parallel bands, a texture that is referred to as foliation.
They are formed when you have a rock that has pressure and heat added to it which creates a different rock. (ex. granite ___ geniss )
Metamorphic rocks may be formed.
No. Granite is an intrusive igneous rock, formed from the solidification of magma underground. Slate is a low grade metamorphic rock formed from heat and pressure applied to deposits of shale, a sedimentary rock.
Schist is a foliated metamorphic rock. It is formed when mudstone, shale, slate, or phyllite are subjected to higher temperature and pressure.
Marble is formed when limestone is subjected to pressure and great heat.
Gniess is formed from pre-existing rocks that are subjected intense derectional pressure.

i think granite because it was formed under the earth in deep pressure and heat but marble has weaker bonds in its particles. marble was formed by limestone with not alot of pressure as granite or heat. granite is way strongger
Greenstone is the rock that has characteristics of both igneous and metamorphic rock.When you break this rock you will see the basaltic composition but it is formed when a basalt is subjected to a different temperature and pressure.
Marble is formed when limestone or dolostone is subjected to heat and pressure deep beneath the surface, so marble is formed from limestone or dolostone.
Metamorphic, I believe. ^_^

Granite does not turn into limestone. Granite is an igneous rock originating from volcanic activity. Limestone is a sedimentary rock laid down in the oceans millions of years ago. Limestone does turn into marble when subjected to huge pressures and heat. It is found areas with a lot of seismic activity like Itlay and Turkey.
