German Antarctic North Victoria Land Expedition III data covers geological mapping, petrography, and geochronology from the 1979-1980 field season. The SCIOPS organization collected this data during a two-phase expedition aboard the M.V. Polar Queen, focusing on the Ross Sea coast and northern Victoria Land. Work included structural analysis, sample dating via Rb/Sr and K/Ar methods, and establishing a base hut in the Terra Nova Bay area.
Use Cases
- Classify rock types like Granite Harbour Intrusives or Bowers Group volcanics using petrography and geochemistry features.
- Model Ross orogenic history by correlating Rb/Sr and K/Ar dating results from high-grade metamorphic samples with structural analysis data.
- Map lithological units and metamorphic grades across specific ranges like the Lanterman or Daniels Range using field mapping coordinates.
- Analyze sedimentology and geochemistry of upper Precambrian and Cambrian sediments for paleoenvironmental reconstruction.
Strengths
- Expedition targeted a specific, logistically challenging polar region with detailed objectives across 8 geological sub-disciplines.
- Fieldwork covered a wide geographic area including the Bowers Mountains, Mariner Glacier, and Coulman Island.
Limitations
- Data is from a single field season in 1979-1980, with no indication of subsequent updates or modern re-analysis.
- Specific sample counts, measurement resolutions, and data formats are unknown from the description.
- Geographic focus is limited to north Victoria Land, not representative of the entire Antarctic continent.
Provenance
- Source
- SCIOPS organization, likely associated with the GANOVEX III expedition.
- Collection Method
- Field observations, sample collection, and laboratory analysis (e.g., Rb/Sr, K/Ar dating) conducted during the expedition.
- Time Range
- 1979-1980 Antarctic field season.

- Geography
- East and north Victoria Land, Antarctica, including specific sites like Lanterman Range, Yule Bay islands, and Borchgrevink Glacier.
