Hydrothermal Minerals | National Museum Wales

Introduction. Wales has an abundance of hydrothermal (literally meaning 'pertaining to hot water') mineral deposits. Hydrothermal activity occurs at many levels in the Earth's crust, from deep-down (a kilometre or more) to the surface (fumarolic deposits around geysers) with hydrothermal fluids generated by igneous, metamorphic and sedimentary processes or a combination of these.
