Granite is an intrusive igneous rock, meaning it has solidified underground as opposed to solidification on the surface.
I am trying to find out what the other two types of rock besides gneiss form the Matterhorn. Gneiss is a metamorphic rock. That's a nice piece of gneiss!
The rock you are likely describing is gneiss, which is a metamorphic rock with alternating light and dark bands. Gneiss forms when intense heat and pressure cause the original rock to recrystallize, resulting in distinct layering of minerals.
When schist is further heated and squeezed, it can form gneiss, another type of metamorphic rock. Gneiss is characterized by its banded texture and high-grade metamorphism.
Granite can be changed into gneiss through the process of metamorphism, where heat and pressure alter the mineral structure of the rock. This process causes the minerals in the granite to recrystallize, forming distinct banding and foliation characteristic of gneiss. The original minerals in the granite are reorganized into new minerals such as mica, quartz, and feldspar, giving gneiss its unique appearance.
Shale is a sedimentary rock, not a metamorphic rock.
Metamorphic, because it is formed with heat and pressure
A Gneiss is a Metamorphic rock
Gneiss is a rock, not a mineral.
Metamorphic
It belongs to the Metamorphic rock type.
No, gneiss is metamorphic.
No. Gneiss is a metamorphic rock.
Gneiss is an example of a metamorphic rock.
Obsidian is in the Igneous rock group.
Granite is an igneous rock and gneiss is a metamorphic rock.
A schist rock belongs in the metamorphic rock group.
Gneiss is a metamorphic rock and its parent rock (protolith) could be a granite or schist.
