Regional metamorphic rocks Teacher Earth Science Education TESEP

On the significance of short duration regional metamorphism

Short duration regional metamorphism is a recently observed and poorly understood phenomenon in metamorphic geology In this review it is defined as metamorphism on time scales that limit length scales of the associated thermal anomaly to significantly less than the thickness of the orogenic crust <10 myr or subducted oceanic lithosphere <5 myr

Abstract A subcircular area of about 650 km 2 in northern California and southwestern Oregon is occupied by rocks of the greenschist metamorphic facies called the Condrey Mountain Schist This greenschist terrane is bordered on the east and west by rocks belonging to the amphibolite metamorphic facies that structurally overlie and are thrust

Contact Metamorphism • GeoLearning • Department of Earth Sciences

Argent 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
