What is a non foliated metamorphic rock?

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 such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance.Click to see full answer. Hereof, how does non foliated metamorphic rock form?Nonfoliated metamorphic rocks are formed around igneous intrusions where the temperatures are high but the pressures are relatively low and equal in all directions (confining pressure).Furthermore, what is a foliated metamorphic rock? Foliation in geology refers to repetitive layering in metamorphic rocks. More technically, foliation is any penetrative planar fabric present in metamorphic rocks. Rocks exhibiting foliation include the standard sequence formed by the prograde metamorphism of mudrocks; slate, phyllite, schist and gneiss. In this regard, what are three examples of non foliated metamorphic rocks? Non-foliated metamorphic rocks are classified based primarily on their composition. Marble, quartzite, and soapstone are examples of non-foliated metamorphic rocks. Marble (left) and quartzite (right) are non-foliated metamorphic rocks.What are non foliated rocks used for?One common nonfoliated meta- morphic rock is marble, which develops from limestone. Marble is used as a decorative stone. It is good for carving and sculpting. Because marble is nonfoliated, it does not split into layers as an artist is working with it.
