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 …

The mineralogy and chemical composition of native gold from twenty-seven representative
orogenic gold deposits were investigated using optical microscopy, electron probe …

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) …

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 …

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 …

Although tourmaline is common in pegmatite-related Nb-Ta deposits and metasedimentary
cover rocks in the Lianyunshan Complex of northeastern Hunan Province, South China, its …

We present a petrographic and geochemical study of tourmaline from the Triassic
Chacaltaya Sn-polymetallic district in the Cordillera Real of Bolivia. Tourmaline is …
