A world-wide resource for interpretation
Global Basement Terranes, a world-wide, cost effective interpretation GIS solution containing over 1300 continental basement terranes, is a culmination of over 12 years' research, data collection and interpretation; documenting the type, age, general composition and tectonic history of basement terranes for every continent.
Global Basement Terranes provides new venture teams with the foundation for understanding the relationship between basement terranes, the overlying sedimentary basins and their petroleum systems. The framework enables more accurate predictions of the occurrence and distribution of petroleum play elements.

Proven methodology
Mapping basement terranes
All basement terranes are mapped from the detailed integration, processing and interpretation of georeferenced scientific and publically available datasets including:
- Gravity and Magnetic Data
- Digital Elevation Model (DEM)
- Terrane Maps georeferenced from literature
- Geological Maps (e.g. USGS, One Geology, Country Surveys)
- Well Data
- Seismic Data
A Global Basement Terranes license includes a tectonostratigraphic summary of each basement terrane derived from our extensive up-to-date literature review, and supplemented by our potential field interpretation. Collectively, the Global Basement Terranes database provides an understanding of terrane formation and deformation through time, and helps to improve plate reconstructions.
Our approach to terrane interpretation
Attributing terrane type and age can be somewhat ambiguous with many different ways of attributing these parameters to a terrane depending on the information available. Complex geological history can result in a terrane that may be defined by several types or be assigned different ages.
For example, an island arc terrane that is accreted along with its associated basins and accretionary wedge and subsequently intruded by a continental arc, does not fit nicely into a single terrane type. Ambiguity in age arises from protracted deformation or thermal history or deformational/thermal events that only affect a portion of the terrane.
Global Basement Terranes provides a solid foundation for regional assessment and prioritisation of exploration areas. The tectonic history
combined with the general composition and terrane type provide the basis for evaluation of rheology, which can then provide key information for basin modelling.
Global Terranes is available as pre-defined subsets as shown on the map above. The inset image shows a sample of terranes coloured by terrane type.Oceanic terranes are not shown on the image.
