Ranges of Physical Parameters and Geochemical Features of Mineralizing Fluids at Porphyry Deposits of Various Types of the Cu−Mo−Au System: Evidence from Fluid Inclusions Data

The paper reviews and summarizes data on the physicochemical parameters chemical features of mineralizing fluids at porphyry deposits Cu–Mo–Au system. calculated average values ranges in mineral-hosted fluid inclusions are as follows: temperature 90–957 °C, 388 °C; salinity 0.1–88.0 wt % equiv. NaCl, 29.4 NaCl; density 0.38–1.85 g/cm3, 0.93 g/cm3. highest maximum homogenization temperatures were detected Cu (Au) type, with both systematically decreasing transition to Cu, Mo (Au), then Au types deposits. situations their analogous. literature concentrations some elements still insufficient reliably characterize variations these all discussed Fe found type. deposits, Ag occurred composition is, thus, strongly correlated hypothesis is discussed: geochemical specifics various system related depths which separated from magmatic melt. A scenario proposed for separation granite melt that form different
