Cape Denison Rock Samples From 2010-2011 Expedition

Two rock samples were collected at Cape Denison, Antarctica, during the 2010-2011 Mawson's Huts Foundation Expedition by Dr. David Tingay. The samples consist of Cape Denison Orthogneiss and Cape Denison Amphibolite, which are approved Geoscience Australia lithological names. Results were published in AusGeo News in December 2011 and are discussed in a related geological map.

Use Cases

• Analyze the spatial distribution of rock types using the provided latitude and longitude coordinates for samples 2122491 and 2122492.
• Validate the lithological classification of Cape Denison Orthogneiss and Cape Denison Amphibolite against established geological maps.
• Correlate sample collection locations (west side of Memorial Hill, adjacent to Granholm Hut) with historical expedition sites.
• Reference the sample identifiers (GA sample_no) for integration with larger Geoscience Australia sample databases.

Strengths

• Precise geographic coordinates (Lat/Long) provided for both sample locations.
• Samples are associated with a specific expedition (2010-2011 Mawson's Huts Foundation) and researcher (Dr. David Tingay).
• Lithological names are formally approved by Geoscience Australia.

Limitations

• Extremely small sample size of only two individual rock specimens.
• No analytical data (e.g., geochemistry, mineralogy) is included in this description; results must be sourced from external publications.
• Temporal coverage is limited to a single collection season.
