Fluid inclusion microthermometry
WebDec 1, 2012 · Fluid inclusion assemblages (FIAs) in quartz, fluorite, and cassiterite are dominantly aqueous, liquid- or vapor-rich, and rarely carbonic-bearing aqueous inclusions. WebFluid inclusion petrography and microthermometry were carried out on 100–120 μm thick, double-polished sections of hydrothermal fluorite and calcite, using a Linkam FT-IR 600 type heating–freezing stage mounted on an Olympus BX-51 type polarizing microscope providing up to 1000 times optical magnification.
