Tectonics and Basin Development of the Offshore Tasmanian Area

A 344-page geophysical monograph from 2004 synthesizing research on the tectonic opening of the Tasmanian Gateway. The volume contains interpretations of geological phases, including rifts, gateway deepening, and ocean changes from the Late Cretaceous to the Neogene. It was published by the American Geophysical Union as part of its Geophysical Monograph Series.

Use Cases

• Modeling past ocean circulation changes based on the described history of the Tasmanian Gateway opening.
• Studying Antarctic glacial development and global climate change over the last 33 million years based on the described geological transitions.
• Conducting stratigraphic investigations of key geological transitions at high southern latitudes as referenced in the description.
• Analyzing Cenozoic marine biostratigraphic and biogeographic development in the Antarctic-Subantarctic region between Australia and Antarctica.

Strengths

• Based on a 344-page peer-reviewed monograph (Geophysical Monograph Series, Volume 151).
• Covers a long temporal range from the Latest Cretaceous to the Neogene.
• Focuses on a key geological region, the Tasmanian Gateway, which influenced global climate.

Limitations

• The primary data format is HTML, which likely presents the monograph text rather than structured data tables.
• Row count and column-level documentation are unknown, limiting suitability assessment for quantitative analysis.
• The dataset's last update is listed as 2026-04-30, which may indicate a metadata error as it is a future date.
