Bronzite Quartzite

Bronzite Quartzite is notable for its unique formation, dating back approximately 2.8 to 2.5 billion years ago, during a time when the earliest life forms began altering the atmosphere by releasing oxygen through photosynthesis. The reaction between iron and seawater led to the creation of oxides that settled on the ocean floor, forming layers of silica and iron. Over time, through various geological processes and the Earth’s evolution, Bronzite was displaced and underwent metamorphosis. It was eventually discovered in Bahia, retaining its high hardness and reddish hues due to the iron in its composition.
