摘要:... Here, we refine the model for orogenic gold formation in the world-class Val-d’Or mining district (Quebec, Canada) using geochemical, isotopic and mineralogical data from quartz-tourmaline-carbonate (QTC) veins from several deposits across the district. Multi-element (Ag, ...

摘要:Abstract(#br)We present 40 Ar/ 39 Ar ages and boron isotopes of tourmalines from a quartz-tourmaline intrusion cross-cutting the Hadean detrital-zircon-bearing metasedimentary rocks from the Mt. Alfred and Brooking Hills localities of the Illaara Greenstone Belt, Western Aus...

摘要:Abstract(#br)Tourmaline is a common accessory mineral in the metasedimentary Pfitsch Formation located in the Pfitscher Joch (Passo de Vizze) area in the Tauern Window of the Eastern Alps. These post-Variscan metasedimentary units experienced peak metamorphic conditions of ~ 55...

摘要:Abstract(#br)Tourmaline is an important B-bearing mineral in many types of hydrothermal deposits, and its chemical and boron isotopic signatures shed light on the nature and evolution of the metallogenic processes. Two generations of hydrothermal tourmaline in potassic-altered...

摘要:Abstract(#br)Tourmaline is a locally abundant hydrothermal mineral in the wallrocks surrounding the W-Sn-Cu mineralized veins in the Panasqueira deposit (Portugal) and a minor phase within the veins themselves. Tourmaline chemical and boron-isotope compositions have been dete...

摘要:Abstract(#br)Tourmaline often occurs in boron-rich granites and its genesis is still in dispute either formed from residual boron-rich silicate melt or from magmatic hydrothermal fluids with or without external fluid involvement. Here, we present a systematic investigation of i...

摘要:Abstract(#br)Tourmaline, scheelite, and magnetite from orogenic gold deposits ( n = 22) and glacial sediments ( n = 5) of the Val-d'Or mining district (Québec, Canada) were investigated by Electron Probe Micro-Analyzer (EPMA) and Laser Ablation-Inductively Coupled Plasma-Mass S...

摘要:Abstract(#br)The boron isotopic composition of tourmaline and hambergite (Be 2 BO 3 [OH,F]) from peraluminous ( n = 12), peralkaline ( n = 1), and peralkaline nepheline syenite ( n = 16) pegmatites has been measured by secondary ion mass spectrometry, for which a new hambergit...

摘要:... Considering the spontaneous electric field and in-situ hydrogen production capacity of tourmaline, this mineral was used as an environmental-friendly bio-promoter for dechlorinating mixed culture containing Dehalococcoides spp. in this work. Research results showed that b...

摘要:Abstract(#br)The tourmaline/manganese-iron-cerium-oxide composites prepared by the hydrothermal method was investigated for NOx removal in simulated flue gas. The microstructure of the catalyst has been characterized by X-ray diffractometer (XRD), temperature-programmed reduct...
