The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) dataset provides a 3D resistivity model of the Earth's lithosphere. The model integrates processed data from 224 stations released in phase one (2020), 73 stations in phase two (2023), and two new stations in phase three, concluding in June 2025. This release from Geoscience Australia includes the model in SGrid and geo-referenced TIFF formats, accompanied by a report detailing data acquisition, processing, and inversion methodologies.
Use Cases
- Modeling subsurface geological structures based on 3D resistivity data.
- Informing mineral exploration strategies based on lithospheric architecture insights.
- Integrating geophysical models with other geological datasets for regional studies.
- Studying the electrical properties of the Earth's crust and upper mantle.
Strengths
- Model integrates data from 299 magnetotelluric stations collected over a multi-year project.
- Includes a detailed report describing data lineage, acquisition, processing, and modeling methodologies.
- Provides 3D resistivity models in both SGrid and geo-referenced TIFF formats for different use cases.
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 the specific survey areas in New South Wales and Victoria.
