JEO 113 - Crystalography

Course Objectives

The aim of the course; to understand fundamental principles of crystallography, to give theoretical and application of crystallization, internal order and external forms as first subject of mineralogy, to explain the main headlines related to chemical and physical properties of minerals (crystals). In laboratory; symmetry, face indices and stenographic projection have been thought on the crystals forms. Physical properties have been investigated on natural mineral samples.

Course Description

Definitions of crystal, mineral, mineraloid, crystallography, mineralogy, references and literature for mineralogy-crystallography.
Internal order; one-, two- and three-dimensional order, lattices, space groups.
Crystallization, crystal growth, structure types, structure defects, twinning, habitus.
External form, symmetry, symmetry operations without translation. Translation. Symmetry applications.
