The L216 Boodjamulla–Croydon seismic survey was designed to image crustal architecture from the Western Subprovince of the Mount Isa Inlier, across the Carpentaria Basin and into the Croydon Province of the Georgetown Inlier. The survey comprises three transects routed along existing roads to minimise new ground disturbance and streamline land access, with active engagement across the Burke, Carpentaria, Mount Isa City, Cloncurry and Croydon shires.

The Geological Survey of Queensland (GSQ) and Geoscience Australia (GA) acquired 842 km of seismic data in northern Queensland between 24 July and 3 September 2025. The L216 Boodjamulla–Croydon seismic survey was designed to image crustal architecture from the Western Subprovince of the Mount Isa Inlier, across the Carpentaria Basin and into the Croydon Province of the Georgetown Inlier.

Statement:
The L216 Boodjamulla–Croydon seismic survey was acquired in 2025 under a joint program between the Geological Survey of Queensland (GSQ) and Geoscience Australia (GA), with field operations delivered by Terrex Seismic. Survey design, acquisition parameters, and operational logistics followed the dual-mode day–night methodology applied in recent deep-crustal programs across Queensland and the Northern Territory. All data were subject to GSQ–GA quality assurance and validation workflows prior to release. This product compiles the approved datasets and documentation for long-term public access.

Notes

Purpose
This product provides central, long-term access to all released data and documentation from the L216 Boodjamulla–Croydon deep-crustal seismic survey. It enables users to obtain raw field data, acquisition reports, and future processed datasets as they become publicly available, supporting geological interpretation, crustal architecture studies, and regional exploration activities across northwest Queensland.
