After the discovery of metamorphic coesite in crustal rocks from the Western Alps (Italy) and
the Western gneiss region (Norway) in the mid 1980s of the last century, metamorphic …

A nomenclature for tourmaline-supergroup minerals is based on chemical systematics using
the generalized tourmaline structural formula: XY3Z6 (T6O18)(BO3) 3V3W, where the most …

The extensive P–T stability and the high chemical variability of tourmaline (Tur) together with
its common occurrence in metasediments proves its high potential for petrological and …

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 …

Ultrahigh-pressure (UHP) metamorphism refers to mineralogical modifications of continental
and oceanic crustal protoliths±associated mafic-ultramafic rocks initially formed or emplaced …

Tourmaline studies have expanded in breadth and greatly increased in number since 1977,
when micro-analytical and crystallographic/spectroscopic instrumentation became widely …

The generation, transport, and recrystallization of slab-derived melts/fluids play a critical role
in the deep recycling of elements in subduction zones. While boron (B) isotope systematics …

Subduction of low-density continental crust to subarc depths is generally associated with
preceding subduction of the oceanic slab. However, the original oceanic signature is often …

Serpentinite dehydration in subduction zones plays a pivotal role in geochemical cycling on
Earth. A number of geochemical studies on arc magmas have elucidated the contributions of …

大横路钴铜矿钴的储量为2.7 万t, 它是我国大型的钴矿床, 其经历了复杂的沉积-变质作用,
