Marble is a metamorphic rock that forms when limestone

Serpentinite is a metamorphic rock that is mostly composed of serpentine group minerals. Serpentine group minerals antigorite, lizardite, and chrysotile are produced by the hydrous alteration of ultramafic rocks. These are igneous rocks that are composed of olivine and pyroxene (peridotite, pyroxenite).Serpentine group minerals occur less commonly in some olivine-bearing marbles (ophicalcite ...It is typically formed within volcanic and metamorphic rocks and consists of mostly chalcedony and quartz. Agate is a hard mineral with a waxy surface. Though it can be difficult to identify ...Metamorphic rocks form because of changes in temperature and depth of burial within the Earth in a solid state without actual melting.

Soapstone. Soapstone is a soft, dense heat resistant rock. The metamorphism of ultramafic protoliths forms it. Its primary component is talc with traces of chlorite and carbonates. Soapstone is suitable for curving because it is soft and heat resistant. 2.High pressure (HP) terranes are areas containing eclogites and other eclogite-facies rocks found within many mountains belts, including the Himalaya and the Alps.

These rocks are called eclogites. Metamorphic belts. Regional metamorphism occurs over wide areas of the Earth's crust. The most common metamorphic sequences in relatively young rocks (e.g. younger than 450 Ma (million years old)) occur in fold mountain belts which are produced by tectonic processes associated with the development of these belts....

Rocks above the surface are eroded. Rocks beneath the surface are forced toward the mantle. Rock layers near the surface decrease pressure on layers beneath them. c.

Metamorphic rocks are any rock type that has been altered by heat, pressure, and/or the chemical action of fluids and gases. Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure).White to orange to light red. Soft (H = 1). III.
