The images herein are scans of materials recovered from long term storage at MRT, that apparently resulted from joint interpretation of TASGO lines 1 and 2 by Australian Geological Survey Organisation (now Geoscience Australia) and Mineral Resources Tasmania personnel.

Essentially similar figures have been published previously (Collins et al., 1998, Drummond et al., 1996), however the images made available here are of considerably better quality in both resolution and colour terms.

The original hard copies have not been retained.
