We studied the possibility of using metamorphic diopside-rich and diopside-bearing rocks, virtually devoid of iron, titanium and alkali oxides, in various silicate technologies. Such rocks are widespread in the Precambrian ...
One of the forms in which the relationship between tectonic deformation and metamorphism is expressed is structural and metamorphic zoning, i.e., the regular variation of structural parageneses and deformation styles of ...
