Calcium isotope compositions as a means to trace carbonate recycling
Shichun Huang, S. B. Jacobsen
Abstract
Marine carbonate, an important CO2 reservoir, is continuously sent to the Earth's deep interior at subduction zones, forming an essential part of the global carbon cycle. The pros and cons of using calcium isotope compositions to trace marine carbonates recycled into the mantle are discussed in this Perspective.
