Blueprint Reading for the Machine Trades - Revised (6th Edition) Deformation, magmatism and metemorphism in the Portsoy shear zone, North-East Magmatism was also sporadic; early granodiorite, monzogranite, and leucogranite dikes yield zircon, monazite, and uraninite ages of 50–52 Ma and ± Ma. Widespread lower crustal melting during the latest Oligocene–early Miocene culminated with emplacement of the Baltoro Plutonic Unit in the Karakoram batholith that cuts deformation.
A deformed composite peridotite-pyroxenite xenolith in Pliocene alkali basalts from the Pannonian Basin (Szentbékkálla, Bakony—Balaton Highland Volcanic Field) has been studied in detail. A narrow shear zone of intense deformation marked by porphyroclast elongation and recrystallization runs along the peridotite-pyroxenite contact. The xenolith contains a large volume of euhedral olivine. Dynamic metamorphism is the result of very high shear stress, such as occurs along fault zones. Dynamic metamorphism occurs at relatively low temperatures compared to other types of metamorphism, and consists predominantly of the physical changes that happen to a rock experiencing shear .
Cataclastic Metamorphism Cataclastic metamorphism occurs as a result of mechanical deformation, like when two bodies of rock slide past one another along a fault zone. Heat is generated by the friction of sliding along such a shear zone, and the rocks tend to be mechanically deformed, being crushed and pulverized, due to the shearing. Diancangshan metamorphic massif is one of the four metamorphic massifs developed along the Ailaoshan-Red River strike-slip fault zone, Yunnan, China. It has experienced multi-stage metamorphism and deformation, especially since the late Oligocene it widely suffered high-temperature ductile shear deformation and exhumation of the metamorphic rocks from the deep crust to the .

The Portsoy Gabbro was emplaced into Argyll Group Dalradian metasediments as part of a suite of mafic intrusives that outcrop around the low-P/high-T Buchan metamorphic domain in NE Scotland.

The huge forces that move continents stretch and squash parts of the Earth’s crust., generating earthquakes and building mountains. They cause rocks near the surface to be fractured and faulted.
At greater depth, the heat and pressure involved can cause folding and/or metamorphism. Rocks within the Portsoy Shear Zone are dominated by heterogeneous amphibolite-facies metagabbroic rocks that range from relatively undeformed coarse-grained variants to highly tectonised mylonites, and whose polyphase intrusion spanned the ductile (regional D2) deformation (Carty,Viete et al.,Carty et al., ).
Regional metamorphism is associated with the folding of rocks in mountain building (or orogenic) activity. This occurs when two continental plates collide, as India collided with Asia forming the Himalayas.
Orogenesis = mountain building (= metamorphism + folding + faulting) Topics & Deformation & Metamorphism Page 12 of metamorphism is associated with circulating hot aqueous fluids (with re lated metasomatism) and typically shows an increasing temperature of metamorphism with depth.
Dislocation metamorphism is a type of metamorphism of local extent, associated with fault zones or shear zones. Grain size reduction typically occurs in the rocks, and a range of rocks.

Eocene to early Miocene metamorphism, deformation, and magmatism in the MMB provides evidence that it may have played a key role in the network of deformation zones that accommodated strain during the northwards movement of India and resulting extrusion or rotation of Indochina.

Rocks deformed and metamorphosed in the Permo-Triassic and Early Jurassic were exhumed in the Early Jurassic, while rocks to the northeast in the Finlayson domain were buried, heated and ductiley deformed at mid-crustal levels (~25 km depth) from the Middle.Geochronological constraints on magmatism and polyphase deformation and metamorphism in the southern Omineca Belt, British Columbia.
