This Research Topic on Deep Carbon gathers the advances in our understanding of the slow, deep carbon cycle that, among other factors, controls the habitability of planet Earth over geological time scales. The papers explore different facets of this unifying concept, including the forms of carbon in the deep Earth, whether at shallow or at great depth (methane, abiotic hydrocarbons, carbon mineralogy and petrology, diamonds).
This collection also considers the origins of carbon, whether biotic or abiotic, and includes the origin of terrestrial carbon. Topical questions considered include: How was it delivered and processed on early Earth? How could this relate to the origin of life? Contributing authors will investigate the role of carbon emission by addressing carbon transfers in all geological/tectonics settings – oceanic ridges, seafloor, rifts, arc volcanoes, and others.
Forty-nine scientists contributed to this collection.
