Unbelievable Discovery: "Impossible" Rocks Discovered on Anjouan Volcanic Island
Geologists have discovered an abundance of quartzite rocks on the volcanic island of Anjouan, located in the southwestern Indian Ocean. This is unusual because the island is made of basalt and should not contain quartzite, a sedimentary rock typically found in river deltas. The presence of quartzite suggests that a piece of continental crust was deposited in the ocean basin and raised up by the volcanic activity. The discovery challenges the principles of plate tectonics and raises questions about the island's geological history. Further research is needed to determine the origin and age of the quartzite.
