At the Fabre Minerals stand you can spend hours and hours viewing the huge number of pieces shown, with each of the details that these offer. It is another thing to choose one from among so much variety, one that fits in the collection, both for one's collection criteria and budget

JFD187AP3: From Montjuïc hill in the city of Barcelona itself, these microcrystalline quartzes are a Catalan classic and although I said I would not part with any Catalan pieces for sentimental reasons, I had two of these so much alike that as an exception I'll keep one and release the other. I liked both of them because they have an intense color and the growth bands are more “pictorial” than what is usual from there.
Montjuïc, Barcelona city, Comarca Barcelonès, Barcelona, Catalonia / Catalunya  Spain (±1981)

Specimen size: 6.6 × 4.8 × 4.4 cm = 2.60” × 1.89” × 1.73”

JFD188AP3: Different from the classic 'tin twins' so typical there, and also with a little more luster than usual. I bought it from a collector in Madrid and I liked it for that difference from what is usually seen in that mine.
Penouta Mines, Penouta (San Bartolomé), Viana do Bolo, Comarca Viana, Orense / Ourense, Galicia / Galiza  Spain

Specimen size: 5 × 3.3 × 2.9 cm = 1.97” × 1.30” × 1.14”

JFD189AP3: A kind of forest of very green and very transparent-translucent Fluorapatite crystals. If there were a name to define the piece, it would be: 'showy'. It comes from an important collection and is very well documented.
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (±1970)

Specimen size: 5.3 × 3.5 × 3.4 cm = 2.09” × 1.38” × 1.34”

Fluorapatite with Chlorite

JFD190AP3: Rare, rare, both for its color and for the presentation of the crystals. Despite having seen so many fluorapatites, the truth is that I don't remember seeing another one like this one. Besides, the little 'ball' of Chlorite is intriguing, because I honestly don't know if it is an aggregate of Chlorite crystals or if it is covering some other species.
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (±1997)

JFD191AP3: It's a little love of mine, this piece. The specimen is a floater, it has no damage, everything complete, and everything, both Quartz and Pyrite and even the Muscovite, has quality. As I said, I feel a little love for it.
Minas da Panasqueira, Aldeia de São Francisco de Assis, Covilhã, Castelo Branco, Cova da Beira, Centro  Portugal (±1999)

JFD192AP3: I bought it from Alain Martaud and he told me it came from Bou Bekker, which I can certainly believe because it doesn't look anything like Touissit's. The best thing about it is the 'dragon' form of the Azurite crystals and the fact that the 'dragon' is on matrix.
Bou Bekker, Touissit District, Jerada Province, Oriental Region  Morocco (±2012)

JFD193AP3: With its brilliant luster and very sharp crystals, from among the arfvedsonites that came out for a period of time in the Imilchil area, this was one of the ones I chose, both for its sharpness as well as for its general quality.
This specific specimen has been analyzed, so it is quite certain that it is Arfvedsonite.
Imilchil area, Anti-Atlas, Er Rachidia Province, Drâa-Tafilalet Region  Morocco (01/2012)

JFD194AP3: Very large plate of innumerable Wulfenite crystals with good color and luster. When I bought it, it drew my attention for its size, its color and luster, and the fact that despite having so many crystals the vast majority of them were in good condition.
Sidi Amer, Touissit, Touissit District, Jerada Province, Oriental Region  Morocco

Quartz with Calcite
 

JFD196AP3: Its form is a luxury. The Quartz crystal is long and has a deep twist enabling us to imagine it as a very showy arch, even more so for being on a kind of natural base, also formed of Quartz. Of all the Alpine finds in the Saint-Jean-de-Maurienne area, this one stands out for its attractive deformity.
Le Noirey, Saint-Jean-de-Maurienne, Savoie, Auvergne-Rhône-Alpes  France (1980)

Specimen size: 11.7 × 7.7 × 4.6 cm = 4.61” × 3.03” × 1.81”

For several years the Expominer Show was held in this pavilion, number 6 of the Montjuïc Fairgrounds. It was later moved to pavilion number 1, much larger and with better accessibility

Among the parallel activities held during the Show are the conferences organized by the Grup Mineralògic Català (GMC) where the academic world approaches that of collectors and the general public attracted by the Earth sciences

Looking is irresistible when faced with so much beauty and mineral variety.

Imagining this creature alive and in its habitat is somewhat scary. Luckily we see it here in fossilized mode.

Here are two people who modernized the GMC with their drive and tenacity, leading the Grup Mineralògic Català to a level never before achieved: Frederic Varela and Marti Rafel, Chairman and Vice Chairman of the Group during their mandates

The workshops organized by the GMC are a guaranteed success. In this photo Pep Ignacio is explaining the properties of gypsum crystals to a group of schoolchildren. Judging by their expressions on the image, they are really interested. The future for geologists and collectors seems assured

When the Show was held in pavilion number 6, there were really long queues to enter

One of the workshops that never fails to be popular is on the technique of panning to search for gold. And the fact is that gold fever is never far away… and may still be here! Even Spanish public television is interested in the subject, while the kids are waiting impatiently for their next turn at panning to start

Specimen size: 8 × 7.9 × 2.9 cm = 3.15” × 3.11” × 1.14”

Main crystal size: 1.6 × 1.4 cm = 0.63” × 0.55”

Very fluorescent long & short UV





Viewing specimens as a team, since four eyes see more than two. Yes, a flashlight always helps to better view the nuances that each specimen displays and that can often go unnoticed

Another of Expominer's successes are the temporary exhibits on display during the Show. Curious and more than interesting was the exhibit "Minerals of the Mediterranean", where several private collectors showed off some of their most prominent specimens

Those of us who were lucky enough to know Joan Viñals know what he was like. Those who did not know him should know that the world, including the mineralogical world, is a little better thanks to people like him

Learning in science is based on observation and experimentation, something that that is well developed in children. The future belongs to them

It is never too late to learn or remember the "old" days, with specific lectures on what we like

On an intermediate scale between children and adults, secondary education is of vital importance. Thanks to the GMC (Catalan Mineralogical Group), prizes for research in the geological sciences are awarded, with the collaboration of the sponsors: Kunugi, Fabre Minerals, and Kucera Minerals
