Processes of Magmatic Differentiation in Connection with Paragenetic Features among Rock-Forming Elements in Natural Glass

  • V. V. Gruza


From an analysis of correlation coefficients defining the strength of correlation between rock-forming elements in natural acidic glass, it has been concluded that these rocks are characterized by micro-inhomogeneities due to differentiation of ions in homogeneous melts. The peculiarities of correlations between elements in acid crystalline rocks of a number of intrusive complexes correspond to systematic patterns of correlation among elements in glasses, and these may be satisfactorily explained not only by crystallization differentiation but also by differentiation of ions in homogeneous melts.
