โœฆ Synopsis


Due to periodical modulation of the temperature difference between the solution and growing rooms growth striations in quartz crystals have been induced. These induced striations have been found as smoky quartz coloration striations as A1 containing material has been used. X-ray topographic investigations found these growth striations even in the unirradiated quartz crystal.

Durch periodische Schwankungen der Temperaturdifferenz zwischen Niihrgutund Wachstumsraum wurden Wachstumsstreifen an Quarzkristallen erzeugt. Da Al-haltiges Material verwendet wurde, konnten diese Wachstumsstreifen nach Rontgenbestrahlung als Rauchquarzzentrenstreifen wiedergefunden werden. Rontgentopographische Untersuchungen weisen diese Wachstumsstreifen auch am unbestrahlten Kristall nach.
