Brown - Quartzite
This newly arrived oxygen on the planet reacted with the large amounts of iron present in seawater, which were released by the intense activity of submarine volcanoes of the period. This reaction formed iron oxides that sank to the ocean floor giving rise to layers of iron. When the amount of available oxygen or iron decreased, these reactions ceased, and layers of silica were deposited alongside layers of iron. The repetition of this cycle gives rise to what we see today in the form so striking in the beautiful plates of Bronzite. After being formed, the Bronzite went through several geological events of great importance and followed the entire evolution of the Earth, being moved and metamorphosed, until it was found in the north of Bahia. The iron present in Bronzite is responsible for its high hardness and its reddish colors, which are often vivid and shiny.
