The first data on composition and spectroscopy of quartzife-rousrocks from the Big Tyuters island
Abstract
We conducted complex comparative mineralogical and spectroscopic researches on the quality of quartz raw from the quartzites and associated rocks at the Big Tyuters Island in the Gulf of Finland (Baltic Sea). Various geological and mineralogical studies of quartzites, which were rare in the eastern part of the Baltic shield, and related iron-alumina metasomatites, and also breaking them granitic dykes, revealed the features that they were secondary quartzites formed in the process of carbon dioxide metasomatism under the influence of volcanic fluids. The quartzites are well-processed by a number of characteristics, and according to ESR (electronic spin resonance) data they contained a relatively small amount of Al, Ge, Ti isomorphic impurities and could raise a commercial interest.
