OZ SEEBASE® 2021 is a regional, depth-to-basement model developed and licensed by Geognostics with the input and support of government and industry.
OZ SEEBASE® 2021 includes the Northern Territory SEEBASE® and GIS released by NTGS in January 2021. Papua New Guinea is also included, for the first time, based on Frogtech Geoscience’s 2018 Papua New Guinea SEEBASE Study.
Geognostics has also completed an integration of original interpretation datasets that, with improved gridding technology, now supports a higher grid resolution than previously available.
OZ SEEBASE 2021 is based originally on Frogtech Geoscience’s OZ SEEBASE® (2005) and OZ Proterozoic SEEBASE® (2006) Studies. In this update, basement is defined as the top of igneous or metamorphic crust at the base of undeformed sediments, regardless of age. Note that in deeper parts of some basins, such as the greater McArthur Basin, the deepest section may be metasedimentary.
Updates to OZ SEEBASE® 2021 include:
Addition of the Northern Territory SEEBASE® and GIS released by NTGS in January 2021
Addition of Papua New Guinea based on Frogtech’s 2018 PNG SEEBASE Study
Exclusion of the metamorphosed sediments of the Hamersley Basin and the Adelaide Fold Belt
Evaluation and integration of original interpretations spanning 15 years of SEEBASE construction across Australia
Improved gridding technology supporting higher grid resolution than previously available.
Geognostics welcomes the opportunity to upgrade areas for Clients and Government Agencies. Please contact us for further information to scope and plan an exclusive study.
Geognostics are global experts in SEEBASE® – a depth-to-basement structural model that defines the present-day shape of a basin and the geodynamic evolution of basin systems through time. We use an iterative, ‘bottom-up’ approach to understand the tectonic and structural controls on basin evolution (Figure 2), and the impact of basement response to deformation events on subsidence and sedimentation with the evolving depocenters. Our SEEBASE studies begin with a unique analysis and testing of plate-scale tectonic events and response through time using basement terranes in GEM – the Geognostics Earth Model. This information is then further tested and integrated with basement interpretations to determine the regional response to deformation and to predict actives faults and structures.
OZ SEEBASE is extraced from GEM, The Geognostics Earth Model including Global SEEBASE
