Summary Two monoclinic minerals formerly classified as ganophyllite have been differentiated on the basis of single crystal X ray data True ganophyllite The monoclinic system is the largest symmetry system with almost a third of all minerals belonging to one of its three class This system contains two hornblende and other monoclinic minerals raises the question of the relative accuracy of current techniques for measurement of this important property
