Earth’s geological carbon cycle plays a vital role in maintaining the planet’s climate and supporting life. Often described as a natural “thermostat,” this complex system helps regulate atmospheric carbon dioxide levels and prevents extreme global temperature fluctuations over geological timescales. Traditional models explain this balance through interactions between volcanic degassing, atmospheric CO₂, continental silicate weathering, and carbonate mineral formation.

However, new scientific discoveries reveal that Earth’s carbon cycle is far more dynamic and complex than previously understood. This issue explores emerging theories and alternative mechanisms that may significantly influence long-term climate regulation, including seafloor weathering, organic carbon cycling, ocean alkalinity dynamics, and variations in carbon degassing rates. Researchers continue to investigate the uncertainties surrounding the processes that control Earth’s life-support system and climate stability.

The Variscan orogeny was one of the most significant mountain-building events in Earth’s geological history, occurring between 380 and 300 million years ago during the assembly of the Pangea supercontinent. Through multiple cycles of continental collision, ocean basin opening and closure, and the accretion of Gondwana-derived continental fragments onto the Laurussia margin, the Variscan belt became a defining feature of ancient Europe’s tectonic evolution.

Unlike many other orogenic systems, the Variscan orogen is distinguished by its unusually thick and predominantly magmatic crust, limited mantle involvement, and complex accretionary history marked by pulsed magmatism along major collision sutures. Because Pangea remains the youngest and best-preserved supercontinent on Earth, studying the Variscan orogeny provides valuable insights into the geological processes responsible for supercontinent formation and continental evolution.
