Lithium–strontium isotope and heavy metal content of fluid inclusions and origin of ore-forming fluid responsible for tungsten mineralization at Takatori mine, Japan
fluid inclusion lithium isotope initial 87Sr/86Sr ratio Takatori mine tungsten mineralization
2017/4/11
Ore-forming fluid trapped in vein quartz as fluid inclusions from tungsten ore at the Takatori mine was extracted by a
crush-leach technique. The trace metal content and isotopic composition (δ7Li an...

2017/4/12
Basalts from Logudoro, Sardinia (Italy), showing geochemical features similar to EM1-type mantle source, have been
analyzed for their Li isotopic composition to provide data related to a heretofore u...
Nuclear Magnetic Resonance and X-ray Photoelectron Spectroscopic Investigation of Lithium Migration in Montmorillonite
Lithium Migration Montmorillonite NMR Spectroscopy X-ray Photoelectron Spectroscopy
2011/12/22
Abstract: When Li-saturated montmorillonite is heated to 200?00 癈, the Li ions migrate from interlayer positions to sites in the layer structure. However, the identity of these sites has not been clea...
