Metamorphic Rocks
Metamorphic rocks form through the transformation of existing rock types due to intense heat, pressure, and chemical activity deep within the Earth's crust. This process, known as metamorphism, alters the mineral composition, texture, and structure of the original rocks, resulting in the formation of distinct metamorphic rocks such as marble, slate, and schist. Metamorphic rocks often exhibit foliation, a parallel alignment of mineral grains, and can provide valuable insights into the geological history and tectonic processes that shaped the Earth's crust over millions of years.
