Abstract

Controversy continues to surround the relative contributions of magmatic versus metamorphic and crustal versus mantle components to the fluids which are responsible for the origin of mesothermal gold deposits (e.g. Rock et al. 1989). The recognition that the products of deep-seated alkaline magmatism, such as lamprophyres, are spatially associated with many mesothermal gold deposits (Rock et al. 1989; Rock 1991) has resulted in the detailed study of primary precious-metal contents in these rocks (e.g. Wyman and Kerrich 1989a; Taylor et al. 1994). This chapter reviews some recent studies on primary precious-metal contents in shoshonitic and alkaline lamprophyres, and other potassic igneous rocks.
