Modified date: 23/04/2023. Metamorphic deposits are a type of mineral deposit that forms as a result of metamorphism, which is the process by which rocks are altered due to changes in temperature, pressure, and chemical environment. During metamorphism, pre-existing rocks undergo a process of recrystallization, and new minerals may grow in

Any dolomite- or calcite-bearing limestone may be metamorphosed during regional metamorphism. The typical result is a massive light-colored marble that may later become exposed in beautiful outcrops. Figures 15.16 and 15.17 show two examples – a marble outcrop on Vancouver Island, Canada, and another on Thassos Island, Greece.

· Abstract. The term metamorphism (from Greek μεταμόρφωσισ = transformation) describes all transformation processes by which a rock reacts to changes in physico-chemical condition within the Earth’s interior, especially to changes in pressure and temperature. By these processes, igneous, sedimentary or (already) metamorphic rocks

And, the absence of fluids means that some low-grade minerals cannot form. • Prograde reactions are mostly endothermic, which means they consume heat. The heat that causes metamorphism naturally fuels the reactions. In contrast, retrograde reactions are mostly exothermic – they give off heat. There is no outside energy driving the reactions.
