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 …

This chapter reviews the boron isotopic composition of the ocean floor, including pristine
igneous oceanic crust such as mid-ocean ridge basalts and ocean island basalts and their …

This study presents a petrogeochemical and boron isotope study on tourmaline from the
barren Damai, and the contemporaneous but ore-bearing Dewulu and Meiwu intrusions, to …

Tourmaline is an eye-catching mineral, but even more importantly, it has played a significant
role in the evolution of scientific thought and, more recently, has been recognized as a …

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 …

This study explores the suitability of apatite as a tracer of the source (s), chemistry, and
evolution of ore-forming hydrothermal fluids. This is tested by analysing the halogen (F, Cl …

Variations in the abundances of light stable isotopes, particularly those of hydrogen, boron,
carbon, oxygen and sulfur, were essential in developing mineralization models. The data …

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) …

Tourmaline from 18 orogenic gold deposits and districts, hosted in varied country rocks and
metamorphic facies, was investigated by EPMA (electron probe micro-analyzer) and LA-ICP …
