May 2019Re: Unknown specimen from Penberthy Croft, CornwallReply from Richard De Nul in Identity Help.Correct Steve, I will have another look at the specimen... and yes Kevin the pointed material is probably the same, but ooh so small :--)
May 2019Re: Unknown specimen from Penberthy Croft, CornwallReply from Richard De Nul in Identity Help.Thank you both for your reaction! I don't think it's cerussite or beudantite. The later is much, much smaller at Penberthy and has a different luster.
@ Kevin: It needs identification but it's the only specimen I have.
I was thinking on a mimetite variety campylite which I think has been ...

Sep 2011Re: Green mystery from MontenegroReply from Richard De Nul in Identity Help.Hi list,
Thank you all very much for solving this mystery!
I though too that something wasn’t right when looking at the bottom of the rock.
I bought the rock from some people near a cave (mine?) entrance high in the mountains in the middle of nowhere at the border between Montenegro and ...
Sep 2011Green mystery from MontenegroPosted by Richard De Nul in Identity Help.Dear list,
Is there anybody who might have an idea what this green mineral might be?
It comes from a very small place near Gusinje at the border of Montenegro and Albania.
The rock measures 13cm x10cm x8cm and is well provided with beautiful but often complex crystals (twins?), going from a ...

All those minerals were found very near the spot of picture 127074. I attached part of your map. The point of the arrow should be the exact location.

Dec 2009Re: Grass green mineral from Clitters (Cornwall, UK)Reply from Richard De Nul in Identity Help.Wow, thanks a lot for all these suggestions....
Olivenite is certainly a possibility. Clitters once has been worked for arsenic, arsenopyrite was then very common. Today it’s very rare at Clitters as the dump has been reworked several times. Olivenite is widely spread in Cornwall, but in the ...
Dec 2009Grass green mineral from Clitters (Cornwall, UK)Posted by Richard De Nul in Identity Help.Is there anyone who has any suggestions on this one? The grass green fibrous material has been found at the Clitters Mine dump (Cornwall, UK) last summer. Accompanying minerals are different copper secondary and carbonate fluorapatite, which is quite abundant at this dump.
Thanks a lot for any ...
Dec 2009Re: Unknown boleite mineral memberReply from Richard De Nul in Identity Help.Thanks everybody !
Pseudoboleite (tetragonal), is indeed a very good candidate. Maybe the crystal structure of the unknown (defined as isometric) must be rechecked.
Cumengeite is very well recognised by its flattened pyramids which are quite typical for this mineral.
Thanks to anyone for ...
Dec 2009Re: Unknown boleite mineral memberReply from Richard De Nul in Identity Help.Hi Knut and Rob,

Dec 2009Unknown boleite mineral memberPosted by Richard De Nul in Identity Help.Is there anyone on the list who has suggestions on a boleite mineral member which is polymorph with cumengeite. The substance has the same chemical formulae but a different crystal system. While cumengite is octahedral the question belongs to the cubic system. Both never appear closely together. It ...
May 2010Re: Slag Dumps and FireplacesReply from Richard De Nul in Field Collecting.I.M.A. gives very well the definition of a mineral (web-site IMA). After that definition all substances formed as result in fe. slagmaterial can’t be classified as being ‘a mineral’. However, they share the same chemical formula, the same crystal system... More, they are given the same ...
Jan 2009Re: Relistian Mine, Gwinear, Cornwall, UKReply from Richard De Nul in Identity Help.Thanks everyone for this fast help!
I think Steve is correct about the apatite. I don't think phosphates aren't lickely to find at Relistian Mine. An accicular variety of apatite might be possible but that's only gambling in this case. For now this one stays with a ...
Jan 2009Relistian Mine, Gwinear, Cornwall, UKPosted by Richard De Nul in Identity Help.Hi list,

Sep 2008Re: A mystery from Les Mines des Montmins (France)Reply from Richard De Nul in Identity Help.Thank you all. I'm agreeing with Uwe, however I think the mimetite-pyromorphite has been altered to cerussite. That curienite-francevillite specimen is not analysed. I added a description to the photo.

Mar 2008Re: Unknown minerals from the Egyptian desertReply from Richard De Nul in Identity Help.That's correct, less information is available from the South-Eastern Desert. Might change in the future.
A description can be found on the Canadian Mineralogist Vol 37, but no research has been done in the past of the copper occurrencies.

Mar 2008Re: Unknown minerals from the Egyptian desertReply from Richard De Nul in Identity Help.Thank you very much Uwe!
Turquoise is also my first 'guess'. Is there any 'easy' way to get more security?
Attached is another image, the blue material is on another mystery?
Any idea, what this other mystery might be?
Thanks for all suggestions!

A few years back I've collected this crystal (see attachment) at Madonna di Fucinaia (Etruscian slag minerals) near Livorno, Tuscany, Italy.

Jan 2009Re: Free computer program for collectorsReply from Richard De Nul in General.I'm sure many topics have been written in the past about databases and I assume this isn’t the right topic to start this all over again.
I'm agreeing with Jolyon that software interfacing is most important, certainly in user build database software.
Many years ago I have build myself a ...
Jan 2009Re: Free computer program for collectorsReply from Richard De Nul in General.Very true Jolyon, but this is a very simple and easy freeware program.
There are no export or import possibilities. All (photos,...) goes into one folder. No possibilty to personalise, extend or link the database.

Dec 2007Re: Hemerdon Mine to reopen for Tungsten/Tin mining!Reply from Richard De Nul in General.Oh, Steve, look it at the bright side of life!
If we ‘the Belgians’ didn’t collect the ‘heavy’ minerals and exported them to the continent, your island would sink deeper and deeper until the water rises and reaches your lips.
We only collect those minerals ...
Dec 2007Re: Hemerdon Mine to reopen for Tungsten/Tin mining!Reply from Richard De Nul in General.Wolf Minerals were only listed on the Oz stock exchange in February of this year, so probably without much of a pedigree. A name that popped up as a speaker for Wolf was Ian Bruce.
It is still possible to find beautiful material if you know were the search in this huge quarry. Permission to ...

Dec 2007Palygorskiteb from Devon (UK)?Posted by Richard De Nul in Identity Help.Hi list,
Another mystery for me... and most likely a stupid question, but...

The only possible locality I known is Meldon Quarry at Devon.
However, I can't find any references for Seator.
Is it correct to identify ...
Nov 2007Re: A mineral from Cumbria, Eycott (United Kingdom)Reply from Richard De Nul in Identity Help.Hi all,
Thank you very much to clarify this locality.
I've never heard about Eycott Hill before and I tought the label maybe had writing errors. Confusion then arises easily with Esket Mine or Eskett Quarry, both also in Cumbria.
Thanks a lot... another mystery solved!

Oct 2007Re: A blueish mica from Wheal BetsyReply from Richard De Nul in Identity Help.Hi all,
Thank you very much for your suggestions. Your 'wild' guess wasn't that wild Peter!
I don't think its anatase David, because vivianite and the specimen from the photo is flexible. I might be wrong, but anatase isn't.
Anatase can be found at the New East Wheal Russell mine as very ...
Oct 2007Re: Is this pyrite?Reply from Richard De Nul in Identity Help.Yes, of course... I think its save to label this specimen as pyrrhotite.
