Long-term Landscape Evolution of Groote Eylandt, Northern Territory

Groote Eylandt in Australia's Northern Territory features a landscape of great age. The dataset likely contains evidence challenging previous interpretations of Tertiary uplift cycles, focusing on Cretaceous sedimentary infill and persistent stream networks. It is provided by the Australian Ocean Data Network and was last updated in 2026.

Use Cases

• Model long-term escarpment retreat rates based on the described less-than-500-meter retreat since the late Mesozoic.
• Analyze the impact of the Cretaceous marine transgression on drainage network development as described.
• Study the relationship between palaeovalleys filled with Cretaceous rocks and the Miocene plateau surface mentioned in the description.
• Reconstruct pre-Cretaceous upland plateau and lowland plain forms based on the described maintained general structure.

Strengths

• Focuses on a specific, well-defined geographic location: Groote Eylandt, Northern Territory.
• Description provides a concrete geological timeline, referencing events from the late Mesozoic, Cretaceous, and Miocene.
• Includes a specific quantitative observation: an escarpment has retreated less than 500 meters since the late Mesozoic.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a single island.
