Brief description

The Canobie Airborne Gravity Gradiometer (AGG) survey of Northern Queensland was flown between 24 November and 3 December 2021.
Contracted to Xcalibur Multiphysics, Geoscience Australia undertook the project management, contract management and quality control on behalf of the Geological Survey of Queensland.
The located data, gridded data and quality control reports are contained within this record.

Survey area was centered on latitude 19° 31’ 04” S and longitude 140° 44’ 14” E to the north of Cloncurry. A total of 8 production flights were flown for a combined total of 4,712.4
line kilometers of data and acquired on 1000 m line spacing at 80 m nominal terrain clearance
Quality control was performed by airborne gravity consultant Dr Mark Dransfield on behalf of Geoscience Australia, with his report included here.

The survey was designed to supplement the regional legacy ground gravity data and improve the definition of gravimetric anomalies in a region deemed highly prospective for base metals exploration.
In addition, the AGG survey will provide better understanding of the cover sequence thickness (estimated to be less than 100 m) and characteristics of the underlying basement geology.

The data was released by the Geological Survey of Queensland on March 29 and can be found at https://geoscience.data.qld.gov.au/dataset/gg100099/resource/geo-spa460972-gg100099.

Notes

Purpose
The Canobioe Airborne Gravity survey falls within Geological Survey of Queensland's Mount Isa Airborne Geophysics (MIAG) program, and is an initiative of the Queensland Government’s New Economy Minerals Initiative (NEMI), aimed at attracting explorers into high-potential, shallow-covered greenfield terranes within the Mount Isa Basin.The airborne gravity gradiometry (AGG) survey data will provide a new generation dataset to supplement the regional legacy ground gravity data and improve the definition of gravimetric anomalies in the region. In addition, the AGG survey will provide better understanding of the cover sequence thickness and characteristics of the underlying basement geology.
