Geognostics is an international team of geological, geophysical and geospatial experts based in Australia and Europe. 

Collectively, the team has many decades of global experience in basement and basin interpretation, structural geology, plate tectonics, geodynamic processes, potential field geophysics, seismic stratigraphy, basin analysis, petroleum systems and GIS.

Geognostics are experts in bottom-up basin analysis that leverage and integrate our unique, in-depth understanding of basement and basin systems via GEM™, the Geognostics Earth Model


GEM, the Geognostics Earth Model

At Geognostics, we have a unique understanding of our world that is encapsulated in GEM, the Geognostics Earth Model. GEM is a collection of modules that provide a new view of global geology.

GEM modules provide a spatially consistent, bottom-up, map-view of global geology that enables explorers to critically evaluate geology and traditional exploration data (well and seismic) in a new light.

Collectively, the GEM Modules provide a predictive framework to understand both basement and basin resources, and to significantly reduce exploration risks.

Global SEEBASE is a high-resolution sub-surface geospatial model that defines the 3D geometry of basement and provides insights into the structural style and tectonic setting of global basin systems and basement geology. It is built using specialized bottom-up workflows, and a hand-contoured structural interpretation, integrating a range of geophysical and geological datasets.

The GEM Tectonics module is a spatially consistent model of the Earth’s crust built using basement terranes and structures, aimed at understanding basin evolution. The Tectonics Module accurately reconstructs the redefined crustal framework back in time using our proprietary plate model.

 

Basement-Focused Workflow

Geognostics specialise in a bottom-up workflow that uses the integration and calibrated interpretation of a range of geophysical and geological datasets.

  • Literature, Client knowledge and technical experts

  • State-of-the-art geophysical processing, enhancements and imaging of potential field datasets

  • Calibration of geological sources of gravity and magnetic anomalies

  • Interpret basement terranes including their age, nature and boundaries

  • Plate reconstructions using the GEM Crustal Framework and Tectonic Module 

  • Integration of tectonic events and structural responses to define basement and basin evolution

  • Identification of major structures and active faults through time

  • Assessment and integration of crustal architecture

  • Gravity and magnetic modelling

  • Depth calibration of interpreted basement to seismic, wells, outcrop, published cross-sections


Deliverables include interpreted datasets developed throughout the workflow.

 

SEEBASE® Depth to Basement is a unique, geologically-constrained interpretation produced through digital GIS-based contouring  and 2D/3D visualisation by  structural and tectonic experts integrating a wide variety of supporting and constraining datasets.

SEEBASE® Depth to Basement is not the output of computational processes or an algorithm such as gravity inversion.

Depth to basement calculated from Laske and Masters, 1999.

Depth to basement calculated from NGDC Sediment Thickness v2
