"Revealing Earth's Hidden Mysteries: Groundbreaking Study Sheds Light on Deep Carbon and Chlorine Cycles"
New research led by Macquarie University earth scientist Dr. Chunfei Chen reveals that Earth's gradual cooling has had a profound impact on the deep cycling of carbon and chlorine, altering their behavior from the surface to the interior. This shift in understanding has implications for Earth's geological history, climate evolution, and the development of life. The study suggests that subduction of massive tracts of carbonate sediments, rather than average sedimentary rock, played a significant role in these cycles. The findings provide insights into the conditions on early Earth and could also help us understand conditions on other planets like Mars.
