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 …

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

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

Abstract© 2018, Czech Geological Survey. All rights reserved. Tourmaline uniquely records
evidence of its geologic history in its composition and, if properly decoded, provides insight …

Tourmaline supergroup minerals with fibrous morphology record and respond to changing
conditions in fluid-rich hydrothermal environments. Based on published data, hand …

Hourglass sector zoning, and related polar overgrowths, are common features of
metamorphic tourmaline, developing as a result of variations in element preference on the …

Detrital tourmaline grains and their associated tourmaline overgrowths provide a means to
unravel the provenance and petrogenetic history of low grade clastic metasedimentary …
