Tourmaline-supergroup minerals are ubiquitous accessory minerals in rocks of the Earth's
crust. They can adjust their composition to suit a wide variety of environments, and therefore …

In order to understand the age and tectonic framework of Eastern to Peninsular Thailand
from the viewpoint of basement (metamorphic and plutonic) geology, the LA-ICP-MS U-Pb …

We revisit the origin of the metamorphic field gradient exposed in the Ryoke Belt (SW Japan)—
the type locality for low pressure/high temperature (LP/HT) conditions—based on combined …

The formation of large porphyry Cu deposits requires shallow intrusion of felsic stocks that
are injected into the focused sites of the mineralization. The parental magmas for these …

A unique assemblage of B-rich rocks (< 2 wt.% B) containing the borosilicate minerals
tourmaline (Tur), prismatine (Prs) and grandidierite (Gdd) is exposed in the ca. 1000 Ma …

Tourmaline is a ubiquitous accessory phase in rocks spanning a wide range of P–T–X
conditions; owing to its compositional sensitivity to variations in such conditions, it is …

We report contrasting pressure–temperature–time (P–T–t) paths of migmatites developed in
the highest‐grade metamorphic zone (Grt–Crd zone) and the contact metamorphic zone …

Behavior of zircon at the schist/migmatite transition is investigated. Syn-metamorphic
overgrowth is rare in zircon in schists, whereas zircon in migmatites has rims with low Th/U …

Hydrogen and B input throughout the Earth's mantle is continuously fed through a sequence
of dehydration and breakdown reactions of hydrous and B-bearing mineral phases stable at …

Mode of occurrence and chemical composition of tourmaline in pelitic schists from the Main
Central Thrust (MCT) zone of the Lesser Himalayan Sequences (LHS) are described in …
