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 …

Orogenic style gold mineralizations in the Archean Hattu Schist belt (E Finland) are present
in all major host rock lithologies including epiclastic sedimentary and volcanogenic rocks, as …

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 …

White mica and tourmaline are the dominant hydrothermal alteration minerals at the world-
class Panasqueira W–Sn–Cu deposit in Portugal. Thus, understanding the controls on their …

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

Abstract The Dachang Sn-polymetallic ore district in South China is the second largest tin
district in the world with a tin reserve of over one million tonnes. Zn-Cu skarn and stratiform …

Owing to the superimposition of water-rock interaction and external fluids, magmatic source
signatures of ore-forming fluids for vein-type tin deposits are commonly overprinted. Hence …

We present coupled textural, elemental, and boron isotopic data of tourmaline from the large
Zhunuo–Beimulang collision-related porphyry copper deposits (PCDs) located within the …

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 …
