DYNAMIC METAMORPHISM Meaning and
Definition
-
Dynamic metamorphism is a geological process that occurs when rocks undergo significant changes in their mineralogy, texture, and structure due to the application of high pressure and temperature during intense deformation or tectonic activity. It is commonly associated with the formation of mountain ranges, as well as other regions experiencing intense crustal deformation, such as fault zones or convergent plate boundaries.
During dynamic metamorphism, rocks are subjected to extreme mechanical forces, causing them to recrystallize and reorganize their mineral composition. This process typically involves the formation of preferred orientation of minerals, resulting in the development of foliation or lineation within the rock. As the rock undergoes deformation, the mineral grains may rotate, deform, or transfer elements between neighboring grains, leading to the development of new minerals or the modification of existing ones.
The changes brought about by dynamic metamorphism can be observed through the alteration in the rock's texture, such as the formation of elongated minerals aligned parallel to the direction of stress. High-pressure conditions during dynamic metamorphism may also result in the formation of new minerals, such as garnet or kyanite. Overall, the degree of metamorphic transformation depends on the intensity and duration of the tectonic forces acting upon the rock.
Dynamic metamorphism is an essential process in the geologic cycle, as it plays a crucial role in the development and evolution of mountain belts, the formation of mineral resources, and the redistribution of elements within the Earth's crust.

Etymology of DYNAMIC METAMORPHISM
The word "dynamic metamorphism" is derived from two main components: "dynamic" and "metamorphism".
The term "dynamic" comes from the Greek word "dynamis", meaning power or force. In this context, it refers to the fact that dynamic metamorphism is caused by intense external forces acting on rocks.
The term "metamorphism" comes from the Greek words "meta", meaning change, and "morphē", meaning form. Metamorphism refers to the process by which rocks undergo changes in mineral composition, texture, and structure due to heat, pressure, and chemical reactions over time.
Therefore, "dynamic metamorphism" describes the type of metamorphism that occurs when rocks are subjected to significant mechanical stress, such as tectonic forces, impact events, or shearing along fault zones.
