I believe it's in the Canadian (state/province) Northwest Territories.
If granite were subjected to intense heat and pressure, it would likely change to gneiss, a metamorphic rock. Gneiss forms through the recrystallization of minerals in granite under high temperature and pressure conditions.
Gneiss is a likely prospect.
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.
caves will most likely develop whare caves develop.
they are likely to develop at warm humid areas.
Gneiss is more likely to form at great depths where mountains are being pushed up. This is because gneiss forms through the process of high-grade metamorphism, which requires high pressures and temperatures found at greater depths in the Earth's crust. As mountains are pushed up, rocks are brought to these depths and subjected to the conditions needed for gneiss formation.
Gneiss is a metamorphic rock that meets those criteria.
A Gneiss is a Metamorphic rock
Gneiss is foliated.
Gneiss is foliated and coarse grained
Gneiss is a rock, not a mineral.
No, gneiss is metamorphic.
