Description
The Lord Howe Rise, a 2000 km long submarine feature in the Tasman Sea, is the subject of this preliminary geophysical survey. The dataset, sourced from the Australian Ocean Data Network, includes seismic profiles and interpretations indicating sediment basins up to 4000 m thick and potential petroleum traps. It was last updated on 2026-04-28.
Use Cases
Modeling petroleum trap structures based on described boundary faults and internal basin structures.
Analyzing sediment thickness and basin geometry based on described 20-40 km wide basins with up to 4000 m of sediment.
Reconstructing paleogeographic environments based on seismic evidence of Late Cretaceous wave-base erosion and shallow marine conditions.
Assessing hydrocarbon source rock potential based on described marine and non-marine sediments and indications of higher heat flow.
Strengths
Describes a specific, large-scale geological feature (2000 km long, 300 km wide) with quantified water depths (750-1200 m).
Provides concrete geological measurements, including sediment basin widths (20-40 km) and sediment thicknesses (up to 4000 m).
Includes interpreted petroleum system elements: potential source rocks, traps (fault-bounded, internal, reef), and seal lithologies.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
Provenance
Source
Australian Ocean Data Network, likely incorporating data from R.V. Sonne cruise and DSDP Site 207.
Collection Method
Marine geophysical survey (seismic profiling) and geological interpretation.
Time Range
Focuses on geological history, including Late Cretaceous and Paleocene periods.
Freshness
Last updated 2026-04-28 15:30:16.750035; freshness should be verified.
Geography
Lord Howe Rise in the Tasman Sea, 600-1200 km off the east coast of Australia.
Primary data formats are PDF and HTML; users may need to extract tabular or spatial data from reports.
