The proportions of ferric and ferrous iron in a given amphibole                 are determined by a complex interaction between intensive                       parameters such as temperature and pressure and crystal-chemical                                                                                                parameters such as crystal structure.  Research to determine                    these properties will be continued.  The approach consists of                   experimental treatment of ampbiboles followed by thorough                       characterization of run products by x-ray, optical, wet                         chemical, and spectroscopic techniques.  The results will have                  specific applications in relating the compositions of natural                   amphiboles to intensive parameters in the environment of                        formation.  More fundamental understanding will come from the                   defining of the interralationship between chemical,                             crysallographic, and thermodynamic properties of a major rock-                  forming mineral group.  The end result will be a better                         understanding of amphibole group  minerals and the environments                 in which rocks have formed.
