Fluid inclusion microthermometry
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. WebFeb 24, 2024 · In the late 1950s, it was only possible to determine bulk salinities of fluid inclusions based on microthermometry or from bulk analyses of fluid inclusion-bearing samples. While bulk analysis often provided very precise results, most natural samples contain multiple generations of primary and secondary inclusions, and each of these …
