Hydrothermal Processes and Wall Rock Alteration

2009
In this chapter, I discuss the effects that hydrothermal fluids derived from internal processes have on the ambient lithologies. I begin by describing the main components of a hydrothermal system and models of magmatic-related hydrothermal processes. Circulation of these hydrothermal solutions or fluids, produces physico-chemical changes in the rocks ...
