Phosphorus may have important effects on the bulk phase                         equilibria and distributions of trace elements in alkali                        aluminosilicate melts.  The central mission of this proposed                    study is an experimental calibration of the partition                           coefficients for phosphorus between melt and feldspars  as                      functions of bulk composition, bulk H2O content, pressure, and                  temperature.  Additional studies include (1) vapor/melt                         partitioning of phosphorus, H2O, and alkali aluminosilicate                     components, (2) the structural role of phosphorus in hydrous                    alkali aluminosilicate glasses, and (3) creation of a data base                 for phosphorus contents of natural feldspars.  This kind of                     information will also add greatly to our understanding of                       pegmatites and other felsic residual magmas.
