An 800 million year old volcanic chain discovered in China's Sichuan Basin has created excitement in the scientific community. This discovery opens a new dimension in global competition.

Researchers indicate that this volcanic structure formed due to the subduction of the oceanic crust beneath the continental crust. The magma released during this process reached the surface, creating a long volcanic chain.

Led by Zhidong Gu and Junyong Li, the team used airborne magnetic sensors to reveal the existence of this volcanic structure. The data obtained indicates a belt approximately 700 kilometers long, located about 6 kilometers beneath the surface.

This volcanic arc differs from typical arcs that form in narrow areas near continental margins. Researchers suggest that this difference may stem from a special tectonic process.

The impact of volcanoes on climate is also significant. While volcanic activities release carbon into the atmosphere, chemical weathering in mountains absorbs this carbon. These processes play a critical role in balancing the Earth's carbon cycle and climate.
