Digital coverages derived from this base map include solid geology, regional and contact metamorphism, and a number of interpreted layers featuring the distribution of the dominant lithologies and minerals such as carbonate, graphite, sulphide, haematite and magnetite.
Geophysical layers feature the regional magnetic and gravity coverages in the digital data package.
A set of geochemical layers has been prepared by averaging whole-rock geochemical data with individual units on the geological map. It is a greyscale image providing accurate positional control.
