Is Serpentine Marble Foliated Or Nonfoliated

The major differences between foliated and nonfoliated metamorphic rocks are in the areas of texture appearance and the type of pressure applied during recrystallization.

Is serpentine marble foliated or nonfoliated.

Serpentine group minerals antigorite lizardite and chrysotile are produced by the hydrous alteration of ultramafic rocks. Quartzite is usually nonfoliated and composed of recrystallized quartz. Some examples of non foliated metamorphic rocks include quartzite marble amphibolite and hornfels. Asked by wiki user.

How are metamorphic rocks determined. Start studying foliated regional or nonfoliated contact metamorphic rocks. Non foliated metamorphic rocks such as hornfels marble quartzite and novaculite do not have a layered or banded appearance. The purity of the marble will depend on the purity of the limestone.

Serpentinite is a metamorphic rock that is mostly composed of serpentine group minerals. Learn vocabulary terms and more with flashcards games and other study tools. Sandstone and chert are the common parent rock. Mottled green and gray.

The pressure applied to the reforming rock causes the differences in the way the rock looks once recrystallized and determines whether it will be foliated or nonfoliated. Serpentinite is nonfoliated and composed mainly of the mineral serpentine. 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. May be harder than glass in places.

Foliated metamorphic rocks such as gneiss phyllite schist and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non foliated metamorphic rocks are rocks that have been changed by heat and pressure into rocks with a non layered or banded appearance.
