May 22, 2019 · Contact metamorphism is a type of metamorphism that occurs near intrusive igneous rocks due to heat from magma. Learn how contact metamorphism forms, what rocks are involved, and see examples of metamorphic aureoles and horns.
Contact metamorphism takes place where a body of magma intrudes into the upper part of the crust. Any type of magma body can lead to contact metamorphism, from a thin dyke to a large stock.
As seen in Figure 8.6, contact metamorphism leads to the development of metamorphic zones called contact aureoles, or skarns, that wrap around an intrusion. Aureoles may be anywhere from a few centimeters to many kilometers thick.
Contact metamorphism is a type of thermal metamorphism that occurs near hot intrusive igneous bodies. Learn about the different types of contact metamorphism, such as heat contact, alternation and hydrothermal, and see examples of metamorphic rocks and minerals.
Contact metamorphism is a type of metamorphism that occurs when rocks are heated by the intrusion of hot magma. The heat from the magma causes the surrounding rocks to recrystallize and form new minerals.
Contact metamorphism occurs primarily as a consequence of increases in temperature when differential stress is minor. A common phenomenon is the effect produced adjacent to igneous intrusions where several metamorphic zones represented by changing mineral assemblages reflect the temperature gradient from the high-temperature intrusion to the ...
Contact metamorphism occurs in the vicinity of an igneous intrusive rock as a result of thermal effects of the hot magma. In the classic case, an igneous intrusive body such as a granite intrudes a sequence of sedimentary or metamorphic rocks and produces a contact aureole consisting of several temperature-specific mineral assemblages.
