Changes in the mineralogy and texture of rock resulting from the heat and pressure of an igneous intrusion in the near vicinity.
Alteration of a rock, mainly by heat, which occurs adjacent to a dike, sill, magma chamber or other magma body.
Metamorphism due to heat and fluids from an intruding magma.
(con'-tact met'-a-mor-phism) The metamorphic processes by which rocks at or near their contact with a body of igneous rock are recrystallized or changed to other minerals due to increases in temperature and materials emanating from the magmas and by some deformation connected with the emplacement of the igneous magmas.
Metamorphism that is caused by heat from a magmatic intrusion.
Metamorphism directly related to the intrusion of magmas and takeing place at or near the contact with the molten rock.
Contact metamorphism occurs when the heat from an intruding magma changes the mineralogy and texture of the surrounding pre-existing rock. Heat, rather than pressure, is the primary cause of the metamorphism. Contact metamorphism is usually restricted to relatively shallow depths (low pressure) in Earth. This is because as depth increases, so do pressure and temperature. At depth, there will not be a large contrast in temperature between the intruding magma and the surrounding rock.
Metamorphism which is caused from magma intrusion near the contact with the magma.
Metamorphism caused by heat from an igneous intrusion.
Metamorphism of country rocks adjacent to an intrusion, caused by heat from the intrusion.
The processes by which solid rocks are altered by increased temperatures when they are close to a hot igneous body, such as an intrusion of granite.
Is the small scale metamorphic alteration of rock due to localized heating. It is usually cause by an igneous intrusion like a sill or a dyke.
