"lava"
It solidifies.
When old rocks are partially melted or squeezed, they can form metamorphic rocks. Examples include gneiss, schist, and marble. These rocks exhibit new textures and compositions due to the heat and pressure they have experienced.
Gneiss typically contains crystals of quartz, feldspar, and mica. These crystals are aligned in layers or bands, giving gneiss its characteristic banded appearance.
Yes, you can. Gneiss is quite similar to granite.

Gneiss is foliated.
A Gneiss is a Metamorphic rock
Gneiss is a rock, not a mineral.
Gneiss is foliated and coarse grained
No, gneiss is metamorphic.
Gneiss is a part of the earths lower crust. No matter where you drill you will eventually uncover gneiss.
