Collection of thin sections and polished sections from Alaska (DGGS) The legacy thin section collection represents petrographic thin sections collected by DGGS geologists for field projects involving geologic mapping in areas of Alaska with a focus to study the potential and controls of mineral and energy resources. As part of the mapping process, rocks were collected for petrographic work to provide information for discriminating between various rock types and to write unit descriptions of the final rock types or units represented on geologic maps resulting from the field work. The collection represents 27 years or more of work and over 15,000 outcrop thin sections from all over Alaska and a wide variety of field geologists. Samples are housed in various locations within the DGGS...
