Tourmaline typically forms where crustal rocks interact with migrating hydrous fluids or
silicate melts, and its isotopic composition provides a reliable record of the isotopic …

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

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 …

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 …

Tourmaline occurs in diverse types of hydrothermal mineral deposits and can be used to
constrain the nature and evolution of ore-forming fluids. Because of its broad range in …

Tourmalines form the most important boron rock-forming minerals on Earth. They belong to
the cyclosilicates with a structure that may be regarded as a three-dimensional framework of …

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 …

Tourmaline group minerals have graced the cabinets of mineral collectors and museums for
untold generations. Their colors and color patterns, along with their diverse shapes and …

Experiments with tourmaline-group minerals began with synthesis, and later, synthesis with
the aim of defining pressure–temperature limits on the stability fields of end-member …

Tourmaline developed under low-temperature conditions (<~ 300° C) typically has
distinctive morphological and chemical characteristics that reveal significant information …
