GEOsciences

  (Formerly Journal of the Czech Geological Society)

Studies of chemical composition, compositional variations, evolutionary trends, textural and paragenetic relations of rock-forming and accessory minerals. The papers dealing with accessory minerals contribute mainly to the crystal chemistry and various genetic aspects of niobium–tantalum oxide minerals, niobian rutile, zircon, thorite and tourmaline. Significance of mineral chemistry of clinopyroxene as a record of the crystallization processes of basaltic magma is demonstrated. The geochemical evolution of granite–pegmatite systems is documented by chemical composition of micas.
