Simulation of the Reactions Between Crustal and Mantle Lithologies Under Fore-Arc Mantle Conditions

Dr. Fatma Gülmez from the Department of Geological Engineering with a team of scientists from Johannes Gutenberg University Mainz, Germany and Australia Macquarie University in Sydney have published their experimental results in Scientific Reports. Using a piston-cylinder apparatus and a novel experimental approach, they conducted high-pressure, high-temperature experiments to simulate the reactions between crustal and mantle lithologies under fore-arc mantle conditions.  They were able to produce carbonatitic and silicic melts interacting with peridotitic upper mantle to form metasomes as a mantle reservoir for the silica undersaturated ultrapotassic melts.
