Tectonic and Sedimentary History of the Argo Abyssal Plain

About 2800 km of bathymetric and seismic reflection profiles cover 110,000 km² of the Argo Abyssal Plain in the eastern Indian Ocean. The data reveal newly identified structural features like the 400-450 km long Joey Graben and document tectonic evolution from the Late Jurassic to the Miocene. Five sedimentary sequences have been correlated with lithology from ODP Site 765 and DSDP Site 261.

Use Cases

• Mapping major structural features like the Wombat, Joey, and Kivi Grabens based on seismic reflection profiles.
• Analyzing sediment thickness and depositional trends across five identified stratigraphic sequences.
• Modeling crustal subsidence and tectonic activity from the Late Jurassic to the Miocene.
• Correlating regional seismic sequences with lithology from specific Ocean Drilling Program sites.

Strengths

• Covers a large spatial area of approximately 110,000 square kilometers.
• Profiles total about 2800 km, providing substantial linear coverage for analysis.
• Identifies specific, newly documented structural features with dimensions (e.g., Joey Graben is 400-450 km long).

Limitations

• Column names and specific data structure are unknown, limiting detailed technical assessment.
• License, author, and precise row/size metadata are not provided across sources.
• The dataset appears to be a published analysis (PDF/HTML) rather than raw, machine-readable data.
