Usually, the margins of continents and locations of mountain building will be the areas wherever metamorphic procedures progress with depth. But in reasonably tranquil spots, exactly where sediments accumulate at slow charges, a lot less magnificent alterations also manifest in reaction to improvements in tension and temperature circumstances. Metamorphic rocks are as a result distributed through the entire geologic column.

Many of such types are repeatedly related to each other in Area and time, nonetheless, reflecting a uniformity of geologic processes over hundreds of many yrs. One example is, the metamorphic rock associations that formulated within the Appalachian Mountains of eastern North The united states in response on the collision between the North American and African lithospheric plates through the Paleozoic Period (541 million to 252 million yrs back) are similar to people who formulated from the Alps of south-central Europe over the collision involving the ecu and African plates that happened over the Mesozoic and Cenozoic eras (252 million yrs in the past for the present).

The conversion of sediment to rock is termed lithification.
