The results of the mineral, chemical composition and structure of fine-grained natural mineral aggregates investigation — minerals of the natural salts subclass of sulfuric acid in the hypergenesis zone of the Sopka Bolshaya (Sherlova Gora) and Kliuchevskoye deposits are presented. With the help of flame atomic absorption spectrometry and turbidimetry, the chemical composition of mineral aggregates, which are a mixture of sulfates, is established. It has been proved that cations of magnesium, iron, zinc, calcium and copper with variable content predominate in mineral associations. By the immersion method with the use of a polarizing microscope, confirmed by x-ray phase analysis such minerals as hexahydrite, pentahydrite, starkeite, siderotil, chalcantite, admixtures of gypsum and quartz are diagnosed. Using IR spectroscopy and thermal analysis, it is shown that they all contain crystalline hydrate in their structure |
