Marble Non Foliated Metamorphic Rocks

A metamorphic rock is similar both in mineralogy and texture to its parent rock.

Marble non foliated metamorphic rocks.

Due to geological changes a metamorphic rock of the foliated or nonfoliated type will be created. Non foliated metamorphic rocks not all parent rocks have platy or elongated minerals and when these rocks undergo metamorphism the individual mineral grains do not align. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Types of non foliated metamorphic rocks include marble quartzite and hornfels.

Marble is a non foliated metamorphic rock that is produced from the metamorphism of limestone or dolostone. Marble is typically not foliated although there are exceptions.

The specimen shown above is about two inches five centimeters across. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth s crust. Hornfels have no specific composition while amphibolites are formed from hornblende and plagioclase.
