    • n diorite The name given by Haüy to a rock included among those varieties which had before that time been generally designated by the name greenstone. Diorite consists essentially of a crystalline-granular aggregate of a triclinic feldspar and hornblende, in very varying proportions, with which are frequently associated magnetite and apatite, and sometimes mica. This rock has usually a thoroughly crystalline structure. Many of the rocks called by the name of diorite are, in all probability, altered basalts; some, however, may have resulted from the alteration of andesites, and even of gabbros. In the case of diorite, the alteration has proceeded further than it has in the diabases and melaphyres, See greenstone and diabase.
