Geoscience Australia Data provides a geological study on the long-term landscape evolution of Groote Eylandt in the Northern Territory. The description challenges previous Tertiary uplift models with evidence of Cretaceous sedimentary rocks in palaeovalleys. The dataset, last updated in 2026, is available in PDF and HTML formats.
Use Cases
- Model long-term landscape stability based on evidence of minimal escarpment retreat since the late Mesozoic.
- Analyze the impact of the Cretaceous marine transgression on drainage network development as described.
- Study the relationship between Cretaceous sedimentary infill and plateau surfaces of supposed Miocene age.
- Reconstruct palaeovalley systems based on the described geological evidence traversing the island.
Strengths
- The description provides a specific geological hypothesis and counter-evidence for landscape evolution.
- Includes a concrete spatial reference to Groote Eylandt in the Northern Territory.
