The objective of this project is to develop an experimental             basis for understanding the behavior of volatiles in submarine                  basaltic magmas.  The principal investigators will measure (1)                  solubility of carbon dioxide over a range of mid-ocean ridge                    basalt compositions, temperatures and pressures; (2) solubility                 of water over the same parameter range and determine the effect                 of water solubility on that of carbon dioxide; (3) kinetics of                  bubble nucleation and growth.  During these experiments, the                    Fe2+/Fe3+ ratio will be determined in order to unravel the                      effects of degassing on oxidation state of the magmas.                          %%%                                                                                     Magmatic volatiles control the style of volcanic eruptions.             Experiments such as the ones to be carried out in this project                  will provide fundamental data on the solubility of two critical                 volatiles in magmas, water  and carbon dioxide.  These data will                help to understand how magmas degas as they ascend and erupt and                to determine if kinetic fractionation among volatile species                    occur during bubble growth.
