Microthermometry is a widespread method of determining the chloride concentrations of saline fluid inclusions and remains the most reliable method for converting quantitative cation analyses (e.g. from LA–ICP–MS experiments) into absolute concentrations. For most saline fluids solute concentrations have been calculated as an equivalent weight percentage of NaC on the basis of phase transition t...

The giant Gejiu Sn–Cu polymetallic ore deposit is one of the largest Sn producers in world, and related time space to highly evolved S type granitic intrusion. mineralization processes can be divided into four stages: (I) skarnization; (II) greisenization; (III) cassiterite–sulfid; (IV) cassiterite–tourmaline–quartz. Five types fluid inclusions were recognized using optical petrography, microth...

Quartz from the stockwork zone of various Cyprus type volcanogenic massive sulfide deposits (Boccassuolo, Reppia, Campegli, Bargone and Vigonzano) unmetamorphosed, Jurassic Northern Apennine ophiolites was studied in order to provide details on submarine hydrothermal conditions characteristics for ore formation. Our detailed SEM-CL investigation quartz contributed a robust characterization inte...

Abstract The paleosalinity of water from which the gypsum precipitated during Messinian salinity crisis is a controversial issue. Recent microthermometry studies on primary fluid inclusions in provided very low values not compatible with precipitation seawater, and suggested strong mixing between seawater nonmarine waters enriched calcium sulfate. We applied new microthermometric protocol cryst...
