How many types of metamorphism are there?
There are four types of metamorphism. Contact metamorphism is a result of heat generated from a nearby magma source. Regional metamorphism consists of change through intense heat and pressure. Hydrothermal metamorphism is a chemical change that occurs when hot fluids circulate through out the rock. Finally fault zone metamorphism is change that happens along fault lines. What features are present in metamorphic rocks? When looking at metamorphic rocks things to look for include Foliation and the type of foliation present. Foliation types include; rock cleavage, schistosity, gneiss, and non-foliated. Metamorphic rocks are broken down into two groups based on whether the rock is foliated or non-foliated. Can any rock be changed into a metamorphic rock? Yes, any rock can be transformed into a metamorphic rock. In fact the parent rock (the original rock) is very important in the metamorphic process. The parent rocks makeup determines what metamorphic agent will change the rock. Some common
