Ultrahigh-temperature (UHT) metamorphism is the most thermally extreme type of crustal
metamorphism, with the crust capable of withstanding temperatures≥ 900° C. Mineral …

Ultrahigh temperature (UHT) metamorphism is the most thermally extreme form of regional
crustal metamorphism, with temperatures exceeding 900° C. UHT crustal metamorphism is …

In general, Archean rocks exhibit rather ordinary moderate-P-high-T facies series
metamorphism; neither blueschists nor any record of deep continental subduction and return …

Partial melting of deep continental crust may occur during either prograde heating or
decompression. Although the effect of temperature on crustal melting has been widely …

Many rare metals used today are derived from granitic pegmatites, but debate continues
about the origin of these rocks. It is clear that some pegmatites represent the most highly …

Regional metamorphism occurs in plate boundary zones. Accretionary orogenic systems
form at subduction boundaries in the absence of continent collision, whereas collisional …

Kyanite‐bearing paragneisses from the Manicouagan Imbricate Zone and its footwall (high‐
P belt of the central Grenville Province) preserve evidence of partial melting with …

Rare kyanite-bearing anatectic paragneisses are found as boudins within sillimanite-
bearing paragneisses of the core of the Namche Barwa Antiform, Tibet. In the present study …

Abstract The Jining Group occurs as the eastern segment of the Khondalite Belt, North
China Craton and is dominated by a series of granulite facies rocks involving 'normal'pelitic …

Pelitic granulites are cropped out in the Daqingshan Complex of the Khondalite Belt, a
Paleoproterozoic tectonic belt in the Western Block of the North China Craton. Petrological …
