Vibranium Quartzite is not a naturally occurring material, but rather a fictional substance that exists in the Marvel Comics universe. Therefore, it does not exist in Brazil or anywhere else in the real world.
If you are referring to quartzite, which is a natural metamorphic rock, its usability for exterior applications in cold climates depends on its properties and durability. Quartzite is known to be a very hard and durable material, similar to granite, and is generally suitable for outdoor applications. However, specific variations of quartzite may have different characteristics, so it is important to evaluate the particular type of quartzite you are considering.
Factors such as the quality of the stone, its porosity, and its ability to withstand freeze-thaw cycles are essential considerations for exterior applications in cold climates. It is advisable to consult with experts such as architects, designers, or stone suppliers, who can provide more detailed information about the specific quartzite you have in mind and its suitability for your intended use.
