Epidote-group minerals rich in rare earth elements (REE), in particular allanite, are common
accessory phases in igneous, metamorphic, metasomatic, and sedimentary rocks. Small …

Epidote minerals are known since the 18th century, but at that time the greenish to dark
colored varieties were termed actinolite or schorl and not distinguished from the minerals to …

Abstract Post-collisional (25–8 Ma) ultrapotassic mafic magmatic rocks occur to the north of
the India–Asia collision zone within the Lhasa terrane of the southern Tibetan Plateau …

Field evidence from the western Tianshan subduction complex in northwestern China
indicates that the high field strength elements Ti, Nb, and Ta were mobilized and thereby …

Abundant zircon grains were found within a metasomatic chlorite–corrensite (trioctahedral
regularly interstratified chlorite/smectite) shell that surrounds rodingite from the Jordanów …

Ductile shear zones can occur as relatively isolated single structures, as arrays, or as
characteristic paired zones. In continuous glaciated exposures of metagranodiorites from the …

The Oligocene–Pleistocene Tethyan Realm Lamproites, from the Mediterranean to
Himalayas, have a clear subduction-related signature and represent one of the most exotic …

The Tianshan is the first locality worldwide where primary fluids at blueschist to eclogite
transition have been documented. Veins containing high-pressure minerals in massive host …

In the subduction complex of the Tianshan mountains, western China, massive blueschist is
cross-cut by an eclogite-facies major fluid conduit surrounded by a reaction zone which is …

The complex vein associations hosted in southern Sulu ultrahigh-pressure (UHP) eclogites
contain quartz±omphacite (or jadeite)±kyanite±allanite±zoisite±rutile±garnet. These …
