Geochemical Data for Ordovician Volcanic Rocks in the Wyalong Area, NSW

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 mid-ocean ridge or back-arc basin setting. The dataset was last updated on 2026-04-30.

Use Cases

• Classifying tectonic settings of ancient volcanic sequences based on geochemical signatures.
• Correlating rock units for regional geological mapping based on described magnetic signatures and stratigraphy.
• Assessing mineral exploration potential by comparing geochemistry to known gold-hosting volcanics like the Gidginbung Volcanics.

Strengths

• Geochemical data is linked to a specific geological formation (Narragudgil Volcanics) and geographic area (south of Wyalong, NSW).
• Data provides context for mineral exploration by noting association with highly magnetic rocks hosting the Temora gold deposit.
• Dataset is hosted by an authoritative national geological survey (Geoscience Australia Data).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified despite the 2026 update date, as the underlying research references work from 1995.
