Abstract: | Etching and optical methods have been applied to study the lineage structure of quartz crystals from the Swiss Alps. It is shown that lineage boundaries form during growth in crystals of high dislocation density by a rearrangement of dislocations in low angle boundaries. The boundaries usually consist of parallel lines and are supposed to be nearly pure tilt boundaries. |
