Work in Progress
Geologic work in progress at Victoria University in connection with the 1960-61 Antarctic Expedition comprises the following three main categories:
|1.||Preparation of geologic map. By the use of oblique aerial photographs, a new semi-controlled base map has been constructed for the entire Koettlitz dry valley area. Geologic data has been transferred to this map. In view of its improved accuracy the new map should be of considerable value not only for the current work but also for future expeditions.
|2.||Petrography - Over 100 thin sections are in course of preparation and examination, for the purpose of studying mineralogy, petrogenesis, and metamorphic facies of rock specimens from the Koettlitz area. A number of thick rock slices will be cut, etched and stained in order to determine their modal content.
|3.||Formal presentation of results - A paper concerning the general geology of the Koettlitz area is planned for publication in the New Zealand Journal of Geology and Geophysics. In addition, separate papers will deal with specific aspects of metamorphism (Dr. Blank), granitic and dike rocks (Mr. Cooper), and Quaternary volcanics (Mr. Willis).
