this granite rock mountain is not only valuable as a tourist destination, but it is also recognized as a major geological site in the world, as named by the international geological congress in 2000.

isotopic studies using sensitive high-resolution technology have recently placed the age of the mountain to be at 560 million years.

these new scientific advances have served to emphasize the site's historical importance.

originally formed underground, its abundant metamorphosed granite is a result of a combination of natural forces, such as weathering, fractures and the climate in rio de janeiro.
