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

Tourmaline sensu lato has been known for at least two thousand years, and its unique
combination of physical properties has ensured its importance to human society, from …

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 …

Tourmaline is the most important borosilicate mineral because of its ubiquity and the
diversity of petrologic information that it can yield. In metamorphic rocks tourmaline can …

Experiments with tourmaline-group minerals began with synthesis, and later, synthesis with

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