Tasmania: Dundas Geological Map

Mineral Matters #538

[Edit: Apologies. I thought I had made the map shareable, but apparently I didn’t! It is now!]

Ah. Dundas, Tasmania. The home of crocoite.

You probably have heard of the main crocoite-producing mines, the Adelaide and the Red Lead, and you may have heard of the Dundas Extended, the Platt, and even the Kapi mines. But have a look at the image below. There are so many mines! Granted, only a few produce crocoite, but there are lots of other minerals too.

Many years ago, I downloaded a reasonably high resolution publicly available copy of the geological map of the area (in pdf format). I don’t remember exactly where I got it from, and I have searched but have been unable to locate the source. Its location may have changed anyway.

So, I have uploaded my copy here if you want to access it.

If you want to find out more about the geology (and mines and minerals) of the area, there are a few online resources available. These include:

• Bottrill, R.S. and Baker, W.E. 2008. A Catalogue of The Minerals of Tasmania. Tasmanian Geological Survey Bulletin 73.

• Elliston, J. 1954. Geology of the Dundas District, Tasmania. Papers and Proceedings of the Royal Society of Tasmania, Volume 88.
