fluid inclusion microthermometry

Fluid inclusion Petrography Quartz and sphalerite samples were initially examined but because the fluid inclusion population in sphalerite samples was far too low for any meaningful study, the work was restricted to samples of quartz. Fluid inclusion homogenization temperatures were measured on double-polished thin sections at ExxonMobil Upstream Research Company (Texas, USA) and Fluid, Inc. (Colorado, USA; Table 3).

Primary Fluid Inclusions 1) Monophase Fluid Inclusions 1) was selected for this study because the The temperature disparity between the fluid-inclusion microthermometry in the Mil Oitavas rutile and the Zr-in-rutile thermometer could rely on the basic assumption of the rutile thermometry, that is, the assemblage rutile-zircon-quartz coexisted in equilibrium (Zack et al. The origin of ore-forming fluids and the genesis of this deposit remains controversial. 60. In ore deposit research, the study of fluid inclusions in gangue minerals such as quartz, carbonates, and fluorite, which are transparent for visible light, is well .
