Update: Information received by Earth Science Australia
indicates that this feature, while very interesting geologically...
It is, in fact, a layered ultramafic intrusion
- we hope to post details in the near future and would like to get in contact with the graduate student from the Queensland University of Technology who looked at it in December 1998 - still waiting....
- for those with an adverturous spirit it is still worthwhile
looking at the convincing information provided below....
