Dislocations in highly perfect quartz crystals have been characterized by correlating experimentally observed section patterns with computer simulations. The Burgers vector observed is the shortest translation vector of the quartz lattice. In cases, such as quartz, where the simple geometrical criteria fail, computer simulation methods are a powerful aid in establishing the Burgers vector of dislocations.
