Contact Metamorphism: When magma comes in contact with other rocks it will heat them and change them into new rocks. This often happens around an igneous intrusion.

What is the origin of lead ore?
the origin of lead ore is contact metamorphic origin
On on what basis can metamorphic rocks be identified?
Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)
How do contact metamorphic rocks form?
Contact metamorphic rocks form when existing rocks are subjected to high temperatures and pressures due to the intrusion of magma or lava. The heat from the molten rock changes the mineral composition and texture of the surrounding rocks, resulting in the formation of new minerals and a variety of metamorphic rocks. This process usually occurs in the shallow crust near the Earth's surface.
At divergent boundaries is what metamorphism results from extrusion of basaltic lava?
A metamorphic rock formed from Basalt is Schist. a.k.a. Green Schist
What processes found at hot spots will form metamorphic rocks?
Metamorphic rocks at hot spots will form mostly by contact and hydrothermal metamorphism as a result of exposure to heat from magma and interaction with hot water respectively.
What are the two types metamorphic rock?
The two groups of metamorphic rock are foliated and nonfoliated. Metamorphic rocks can also be classified as contact and regional.
What rock can form in a contact metamorphic zone?
Hornfels is a common rock that can form in a contact metamorphic zone. It is typically fine-grained and formed by the heat and pressure from nearby igneous intrusions.
What is a zone of contact metamorphism called?
A zone of contact metamorphism is called an aureole.
What are two things a metamorphic rock can d changed into?
regional and contact
How metamorphic rock be transformed into igneous rock?
contact
What is the origin of lead ore?
the origin of lead ore is contact metamorphic origin
On on what basis can metamorphic rocks be identified?
Metamorphic rocks can be identified if the rock is foliated or nonfoliated, foliating type, type of metamorphism (contact/regional), and by probable original rock. :)

A metamorphic rock is from where?
Metamorphic rock usually forms when a rock is altered under heat and pressure without melting. Some rocks may be metamorphosed by contact with hot water,
What kind of metamorphic rock does meatloaf represent?
It would represent a contact metamorphic rock, as the change that has occurred in the raw ingredients has been caused by exposure and proximity to a source of heat.
What is a non-foliated contact metamorphic rock called?
A non-foliated contact metamorphic rock is called a hornfels. Hornfels is called so because of its exceptional toughness and texture both reminiscent of animal horns.
If the sedimentary rock limestone is subjected to metamorphism what metamorphic rock will likely form?
If limestone is subjected to metamorphism, it will likely form marble. Marble is a metamorphic rock that forms from the recrystallization of limestone under high temperature and pressure conditions.
