Plumbophyllite

Hello,Does any person know if -Plumbophyllite and-Unnamed Pb Silicate, are all the same mineral..
Reason I ask is,,Black Star Open Cut ,Mount Isa ,Australia had the Unnamed Pb- Silicate on its mineral list..This was tested and found to be Plumbophyllite..
Plumbophyllite can be clear to blue(Cu content) so??are the two minerals the same.
It also seems a bit lucky that same new mineral(if they are all identical) should be found at the same time on 3 different continents.
Thank you for any help

Hi Con
Good point.
I have sent an email to Steve Rust, who had a couple photos of the unnamed Pb-Si mineral from Wales, to see if he has any info on it we can use to compare with plumbophyllite.
I removed the unnamed Pb-Si mineral from Mt Isa, and added plumbophyllite.
Whilst on Mt Isa, we have a number of sub-deposits under this mine (eg Glory Hole, Kennedy sitstone, Enterprise mine, Rio Grande) with no minerals or info listed - it would be good to add some details if you have any?

Hi Con
I got your samples, many thanks. Unfortunately the blue-green mineral you sent is not plumbophyllite - probably cuprian dolomite.
The plumbophyllite only seems to occur on cerussite.
I will get onto the others.

Ralph
