Geochemical Data for Ordovician Volcanic Rocks in the Wyalong Area, New South Wales

Geoscience Australia Data provides geochemical data for Ordovician volcanic rocks in the Wyalong area of New South Wales. The data indicates these rocks, known as the Narragudgil Volcanics, accumulated in an oceanic environment, likely a mid-ocean ridge or back-arc basin setting. The dataset was last updated on 2026-03-25.

Use Cases

• Classifying ancient volcanic rock settings based on geochemical signatures mentioned in the description.
• Correlating rock sequences for regional geological mapping based on described magnetic and stratigraphic relationships.
• Investigating the geological context of gold deposits based on the association with the host Gidginbung Volcanics.
• Modeling paleo-tectonic environments based on inferred mid-ocean ridge or back-arc basin origins.

Strengths

• Data is associated with a specific geological formation (the Narragudgil Volcanics) and location (Wyalong area, NSW).
• Provides context linking the volcanics to a known gold deposit host (Gidginbung Volcanics).
• Last updated date is explicitly provided (2026-03-25).

Limitations

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