WebDec 1, 2016 · This paper attempts to characterize fluid inclusions over a 4000 m vertical interval and further to unravel their sources and evolution from field observation, ore geology, fluid inclusion and H–O–S–He–Ar isotope analysis at the Sanshandao gold deposit. Based on this information, ore genesis will be discussed. 2. Regional geology WebFluid inclusion studies of MVT deposits and, to a lesser extent, of SedEx deposits have indicated that mineralization typically forms from highly saline brines (15–30 wt.% NaCl) at moderate temperatures (75–200 °C) ( Leach et al., 2005; see Chapter 13.5 ).
