Within a contact metamorphic aureole the grade of metamorphism increases toward the contact with the igneous intrusion. ... Two zones representing different contact metamorphic facies are seen within the aureole. The outer zone contains metapelites in the Hornblende Hornfels Facies, and the zone adjacent to the pluton...

Since only a small area surrounding the intrusion is heated by the magma, metamorphism is restricted to a zone surrounding the intrusion, called a metamorphic aureole. Outside of the contact aureole, the rocks are unmetamorphosed.

On the basis of new demagnetization and rock magnetic experiments, a scattered, two-polarity remagnetization extending throughout the contact metamorphic aureole surrounding the Jurassic Notch Peak granitic stock in western Utah is now thought to reside in metamorphic pyrrhotite rather than in fine-grained hematite.

20, 1. Metamorphic rocks have been changed from their original form by heat or by pressure beneath Earth's surface; for example, limestone to marble, shale to slate, slate to schist. Dislocation metamorphism (a widespread but non-universally recognized concept—see Sobolev et al.

The calculated width of the aureole (180 m) and temperature distribution within the aureole (500 to 620 °C) are consistent with observations. The calculated reaction rates for the These results strongly support the assumption of chemical equilibrium during metamorphism, even in contact-metamorphic aureoles,

A journey through a contact metamorphic aureole: Metamorphism of the Kluane metamorphic assemblage, SW Yukon ... The Ruby Range along the northern Kluane Lake provide a cross section through the contact metamorphic aureole. The structurally deepest and metamorphic lowest grade rocks are in the south (on the right).
