- •
We give a reappraisal of the lithostratigraphy of the central Siguiri Basin.
- •
We support this reappraisal with SHRIMP dating of detrital and igneous zircons.
- •
We suggest that the central Siguiri Basin is part of the Tarkwa Group.
- •
These late basin sediments highlight the early architecture of the Siguiri Basin.
- •
This early architecture can be used to improve orogenic gold targeting.
