(An aureole is the zone surrounding an intrusion, which is a mass of igneous rock that solidified between other rocks located within the Earth.) An analysis of the possible events that evolve in the regional metamorphism of an argillaceous sediment indicates that, if water flow takes place via pore spaces connected to the surface, the water-vapor pressure may be very low and in the extreme case may approach that at the surface. Metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism. Please check your email address / username and password and try again.

Not only does water act as an agent of transfer in metamorphism, but it also acts as a catalyst in many chemical reactions. What type of solvent is needed to remove an oil spot. Some people would include a third agent - fluids - but that is metasomatism. True The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. This is a commonly used classification because there is a genetic relationship between the metamorphic type and the agent of metamorphism.

Every rock contains some water, butsedimentary rocks hold the most. Water pressures lower than the rock pressure cause metamorphic reactions to run at lower temperatures. The role of water in metamorphism is determined by the independent variables rock pressure, temperature, water pressure, and the amount of water present. Near intrusive granite contacts, rocks commonly show obvious changes in color and texture. Experiments have been made under water pressures less than the total pressure.
