Metamorphic rocks form through a process called metamorphism, which involves changing the form or composition of existing rocks due to intense heat, pressure, or chemical activity. These conditions are typically found a few kilometers underneath the Earth's surface and can extend into the upper mantle. During metamorphism, existing minerals in the rock can recrystallize, causing the rock to undergo physical and chemical changes, resulting in the formation of new minerals and textures.
Metamorphic rocks are formed through a process called metamorphism, which involves a change in form. These rocks are found a few kilometers below the Earth's surface and extend into the upper mantle. The conditions necessary for their formation include high pressure, high temperature, and often the presence of fluids.
Metamorphic rocks are formed through a process known as metamorphism, which involves changing the original form of a rock. This process occurs a few kilometers below the Earth's surface and extends into the upper mantle. Metamorphism is triggered by high temperatures, extreme pressure, or the presence of fluids and minerals, leading to alterations in the rock's texture, composition, and structure. The resulting metamorphic rocks exhibit different characteristics than their original forms and can range from foliated rocks with layered textures to non-foliated rocks without distinct layers.
