ODP Site 1167 provides age control indicating the bulk of the trough mouth fan was deposited prior to the Brunhes-Matuyama Boundary (780 ka). The dataset describes the stratigraphy of the Prydz Channel Fan, built by the Lambert Glacier-Amery Ice Shelf system, and is provided by Geoscience Australia Data. It was last updated on 2026-04-30.
Use Cases
- Modeling past extreme ice advances based on debris flow deposit stratigraphy.
- Correlating glacial retreat phases with thin mudstone horizons in the fan record.
- Investigating mid-Pleistocene climate transition causes based on the described change in ice advance patterns.
Strengths
- Age control is provided by ODP Site 1167, referencing the Brunhes-Matuyama Boundary (780 ka).
- The description provides a specific geological hypothesis for the cessation of extreme ice advances.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
Provenance
- Source
- Geoscience Australia Data
- Collection Method
- Likely derived from Ocean Drilling Program (ODP) core analysis and geological interpretation.
- Time Range
- Late Neogene to present, with a focus on events around and before 780 ka.
- Freshness
- Last updated 2026-04-30 15:29:29.997377; freshness should be verified.
- Geography
- Prydz Bay and the adjacent continental slope, East Antarctica.
