Tourmaline group minerals are typically the predominant host of boron in hydrothermal
mineral deposits. Boron is a fluid-mobile element whose isotopic composition reflects many …

Rare-element pegmatites may host several economic commodities, such as tantalum (Ta-
oxide minerals), tin (cassiterite), lithium (ceramic-grade spodumene and petalite), 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 …

Boron is an incompatible lithophile element that is readily transported by granitic melts and
hydrous fluids and therefore is concentrated in the continental crust relative to the mantle …

Tourmaline is nature's perfect forensic mineral. From a single grain, the full geological past
of its host rock can be reconstructed, including the pressure–temperature path it has taken …

Many granitic pegmatites contain two textural domains. Anisotropic textures of the outer
zones, including fine-grained units, graphic intergrowths, and unidirectional solidification …

Abstract The world-class San Rafael tin (-copper) deposit (central Andean tin belt, southeast
Peru) is an exceptionally large and rich (> 1 million metric tons Sn; grades typically> 2% Sn) …

Abstract The Mt Stafford area in central Australia preserves a low-pressure greenschist-to
granulite-facies regional aureole. The metasedimentary sequence has been divided into five …

Detailed analyses of melt and fluid inclusions combined with an electron-microprobe survey
of boron-bearing minerals reveal the evolution of boron in a highly evolved peraluminous …

Tourmaline is widespread in metapelites and pegmatites from the Neoproterozoic Damara
Belt, which form the basement and potential source rocks of the Cretaceous Erongo granite …
