Abstract

The chemical composition of primary individual inclusions in large galena crystals from the Madan ore district, Bulgaria (see Pt. I), is studied in this paper. The liquid phase was analysed for Na, K, Ca, Fe, Mn, Mg, NH sup+inf4 , Pb, Cu, Zn, Al, Cl−, F−, SO 2−4 , HCO −3 , and HS− (+S2−): pH was also determined. The following analytical methods were used: atomic-absorption spectrophotometry, emission spectral analysis, spectrophotometry, nephelometry, microcrystalloscopic and drop reactions. The gas phase was mass-spectrometrically analysed after opening the vacuoles in vacuum. It was found to consist of water vapour and CO2 only. It was also found that the solutions are chloride-sodium-potassium with a total salinity of 4–4.5%. They do not contain measurable amounts of sulphur components. The CO2/H2O ratios vary strongly between the various vacuoles, which is explained by the crystallization in boiling solutions. The problems of the hermeticity of inclusions, the partial pressure of CO2, the temperature of crystallization, and of the possible role of boiling in the ore-forming process are discussed.
