PostPosted: Dec 12, 2021 15:02    Post subject: Unusal Fluorapatite - Silvia's Collection  

Cluster of satiny lustrous translucent prismatic Fluorapatite crystals measuring to 3 cm in size with micro crystallized Topaz, Muscovite and Goyazite. Topaz and Goyazite verified by SEM and XRD.

The Fluorapatite crystals display a ‘mild’ orange fluorescence in the presence of UVA light – not as strong as the fluorescence exhibited by the green crystals of Fluorapatite.

Hi Silvia,

Some photo detail of the Goyazite please, or too small?

Hello Jordi:

The specimen came with a label that stated Goyazite. I have no reason to doubt the analysis, but I am more than happy to organize another SEM/XRD analysis to be positively sure. My partner will look at it under the microscope in the meantime.

PostPosted: Dec 18, 2021 15:30    Post subject: Panasqueira Pictures - Silvia's Collection  

More about Panasqueira

In 1886 the first prospecting licence at Panasqueira was granted, and the first reference to wolframite occurred in 1888. In 1896 a mining company was formed to exploit the deposit. Underground mining operations at Panasqueira have been continuous since 1896, except for a brief period at the end of World War II and a second closure in the mid-1990s.

From 1937 to 2018 a total of 42 million tonnes of rock have been extracted from the Panasqueira ore-body. This rock has produced approximately 132,000 tonnes of tungsten concentrate, 7,100 tonnes of tin concentrate and 34,000 tonnes of copper concentrate.

Despite 100 years of near continuous mining, very little primary exploration has been done outside the active or past mine workings.
Several anomalous areas of elevated tungsten and tin geochemistry were established by a regional stream sediment geochemical survey carried out between from 1982 to 1984 by Beralt. However a “true” exploration of the concession and the area immediately surrounding the concession seems to have been fairly limited.

It is worth noting that the hills surrounding the mine contain many old pits and shafts left from the days of past hand mining operations.

PostPosted: Jan 08, 2022 16:37    Post subject: Photographing Minerals – A Tale of Frustration - Silvia's Collection  

Photographing Minerals – A Tale of Frustration

I thought it would be nice to share some of my adventures with the digital camera. I am not a professional photographer – just barely an amateur one, but I have managed to take some nice photos of some of my minerals.

Polite and constructive criticisms welcome.

Camera

The camera I have used is a Nikon Coolpix A100. It has a 20.1 megapixels sensor, a wide zoom of 5X and a dynamic fine zoom of 10X. Note that I never use the zoom feature when photographing minerals. It has a LCD screen 55 mm long and 42 mm wide. When photographing minerals, this LCD becomes my defacto eye. I never look at the mineral, rather I use the LCD display to show me what the camera sees. If the mineral looks good in the LCD, the camera will take a nice shot. The camera is attached to an appropriate tripod.

Light Box

For most minerals I use a light box made of bright white plastic. It has an LED illuminator that runs off a 5VDC power supply. It is approximately 30 cm x 30 cm x 30 cm in size with a circular detachable top lid. When photographing minerals I flood this light box with light from three to four 240V globes. When the specimen is too large to fit in the box or the box does not give a good photo I will use my computer desk with the appropriate background – white or black cotton sheet.

Light Source

I use 240V/50Hz, 12W E27 globes that emit light described as ‘daylight’ (5500K to 6500K) by the supplier. Each globe is mounted in a lamp fitting that clips to the top of my computer desk.

When using the lamps all exterior light is excluded. The room is dark, and the only light comes from the lamps.

Software

Any photo editing software package can be used, such as Photoshop, Luminar AI, Adobe light room, Aurora HDR and many others. I often use a very early edition of Adobe Photoshop, circa 2010.

Miscellaneous

This includes all and anything I use to get a good photo – blocks of wood, plastic, metal or rubber to support the specimen. Sheets of folded aluminium foil to reflect light and white plastic from discarded milk containers to diffuse the light.

An example

Pyrite, Marcasite and Pyrrhotite are annoying to photograph. You can often get a very nice photograph with every aspect of the mineral in focus, but it lacks the tones that the eye sees in the specimen. I often ask where are the beautiful yellow tones of Pyrite and the bronze velvet tones of Pyrrhotite that I can see in the specimen.

I decided to use the photograph of the specimen of Sphalerite with Pyrrhotite from Dal'negorsk, Russia as an example. I had no success using my light box to photograph the specimen. Many of the photographs taken were in focus with great depth of field but they looked nothing like the specimen I had in my cabinet. So I set up my computer desk to take the photo. I used a white cotton sheet for the background, and I positioned the lights until what I saw in the LCD was what I wanted to photograph.

I used the automatic focus feature of the camera. This places a green box around that part of the subject the camera deems to be in focus. When almost in focus you get a yellow box, and when not in focus a small red box appears in the camera’s LCD.
Sometimes only part of the mineral was in focus, so I made small adjustments to the position of the lights, the location of the camera and the position of any reflectors or diffusers used to take the photograph, until the whole specimen was within the green focus box. And then I took the photograph, and continued with the process until I was happy with all the photographs taken.

Hi Silvia,

really good and showy specimens from Cavnic. I like Romanian minerals and especially Cavnic, a wonderful locality for quartz and sulfide fans - I am both :-)

Regards
Tobi

Many thanks for the encouraging words.

My partner and I are great fans of sulphide minerals too. We love Romanian minerals. It is a very beautiful country with lots of history and folklore and lots of great minerals too.

You have a wonderful collection... and I really appreciate you posting images from serveral parts, details and especially the back of your specimens.
As you say, they often add important info about the way the piece formed and give an idea of the matrix and material the location should be known for.

(I have over my time collecting sometimes bought pieces, where origin isn't clear, and having similar pieces to compare to, not just the crystals, but the matrix can be invaluable in trying to determine a more specific location than given by the vendor)

Silvia, I think I mentioned this before but I have to say it again and agree with Bergur: You are not just showing your collection, you are telling stories and teaching geology and mining history. Highly informative and always a pleasure, you are such an enrichment for this forum!

Best regards
Tobi

Many thanks Bergur and Tobi for your kind words.

For me collecting minerals is not just about good aesthetics, it is about everything associated with the mineral – locality, history, geography, geology, mineralogy and the people. Panasqueira has been very good to me. Great minerals from a still active mine with lots of history. My partner and I also collect material from many worldwide locations, but our European collection contains the most information about the mines and the localities.

I was a teacher, and it is hard to get out of the habit!

Best Regards to all.

PostPosted: Feb 02, 2022 19:17    Post subject: 3D Printing - Silvia's Collection  

Labels and Stands

We are in the process of setting up a high-end (aka expensive unfortunately) 3D printer so we can make high quality labels and mineral stands. At the moment we make our stands out of wood, acrylic or metal, but this can be both time consuming and problematic. A 3D printer may take several hours to make a single stand, but it is doing all the hard work. Most of our labels are printed on quality paper then laminated or etched into metal. We have considered buying an engraver so we can print/etch them on plastic, but that is now the job of the 3D printer.

I have attached a photo of a typical label, and I would welcome the polite input from other members of the Forum regarding their home-brew labels and stands.

Silvia, I really really like that style of labels, very professional and aesthetic!

As a collector who often (in fact TOO often ...) thinks about "the perfect label" this a very interesting discussion for me ;-) There's already a thread about labels, I re-started it now in connection with your post above:

Thanks for reviving this. It is great timing for my efforts as well.

What size do you typically print labels? Same size all specimens regardless of their sizes.

Thanks,
Bob
