Fluid inclusions description

Much research on the Hishikari deposits has been carried out since the discovery of gold veins in 1981. Urashima and Izawa (1983) reported fluid inclusion studies using core samples. Abe et al. (1986) made a detailed description of the veins. The regional geology of this district is described in MMAJ and SMM (1987) and Urashima et al. (1987). 

Without any sophisticated instrumentation, some most important types of fluid inclusion are easily recognized under the petrographic microscope (for a complete and detailed description of the criteria see Roedder, 1972). Most common fluids may be classified as aqueous H2O (Fig. 1.2), H2O + NaCl (Fig. 1.3), H2O + NaCl + many other daughter minerals (l + in Volhynia pegmatite, each a different species, lyakhov, I967), H2O + immiscible hydrocarbons and oil, carbonic (CO2 dissolved hydrocarbons. Fig. l.k and 5) and composite (H2O + CO2, Fig. l.l). Similar in appearance to some of these fluid inclusions are glassy (Clochiatti, 1975) and empty low density gas inclusions, which must be checked by microthermometry (see below). ... 

The analysis presented in Chapter 8 was solely in terms of the conservation equations for the particle phase of a fluidized suspension. However, the full one-dimensional description is in terms of the coupled mass and momentum conservation equations for both the particle and fluid phases eqns (8.21)-(8.24). These equations correspond to those derived in Chapter 7, except for the inclusion of the particle-phase elasticity term on the extreme right of eqn (8.22).
