Local prognosis and criteria for evaluation of Iceland spar occurrences on the basis of mineralogical studies

Abstract

As a result of studying the morphology and optical properties of Iceland spar crystals on an ontogenetic basis, crystal morphological zonality, the relationship between the shape, internal structure and optical properties of the crystal and optical material were established. Identification of the regularity can be used for geological exploration process in the evaluation of prospects of objects and research works.
