Certain time determinations and structural projections relate the fluorspar district deformation to igneous and tectonic activity of the Mis-sissippian Embayment province. The recognition of this relationship permits the statement of a theory of origin of the mineralizing solutions and their fluorine content. It is suggested that the more sharply defined genetic processes of the fluorspar deposits may be applied to problems of ore genesis of other Mississippi Valley provinces
