Is a migmatite foliated or non foliated metamorphic rock?

Difficult to give you a precise answer, migmatites are composed of a leucosome which is new material crystallized from incipient melting and a mesosome which is old material that resisted melting. These two materials may form a fine fabric which imparts a foliation to the rock. The leucosome may also be incoherently folded. Also if the migmatite is forming from a foliated source, the foliation may persist. Thus migmatites are metamorphic rocks that show characteristics of incipient melting and they may or may not show a foliation too, the foliation is not a critical characteristic of a rock being a migmatite.


For metamorphic rocks which forces allow for mineral growth and change within the rock?

heat and pressure


What is a metamophic rock?

a metamorphic rock is a rock that is formed from heat and pressure it can form from a sedimentary or igneous an example of a metamorphic rock is marble metamorphic rocks can have foliation like banding or layers.


How can you determine if a rock is metamorphic?

To determine if a rock is metamorphic, look for signs of heat and pressure altering its original form. This can include changes in texture, mineral composition, and the presence of distinct banding or foliation. Additionally, metamorphic rocks often have a crystalline structure and may contain minerals like mica or garnet. Conducting a mineralogical analysis and examining the rock's physical characteristics can help confirm its metamorphic nature.


How is metamorphic rock formed and what are the processes involved in its transformation?

Metamorphic rock is formed when existing rocks are subjected to high heat, pressure, or chemical changes. This causes the minerals in the rock to reorganize and form new structures. The processes involved in its transformation include recrystallization, foliation, and the growth of new minerals.

What are three types of foliated rock?

Metamorphic rocks are catagorized into two main types: foliated and non-foliated. Three examples of foliated metamorphic rocks are gniess, slate and schist. Some non-foliated rocks include marble, amphibolite and quartzite. Generally, metamorphic rock, and the metamorphic processes can be divided into three categories: regional, contact, and cataclastic.


Where do foiliated rocks form?

Foliation occurs deep underground.
