Mineral chemistry may provide the most effective way of distinguishing lamprophyres from each other and from common igneous rocks. The aim of this chapter is therefore to identify both unusual mineral species and compositional fields of common minerals which are characteristic either of lamprophyres collectively, or of particular branches. Only a broad overview can be attempted in the available space; those interested in fine mineralogical detail can refer to specific reviews such as Bergman (1987), and R.H.Mitchell (1985,1986).
