Posted: Nov 07, 2021 13:18 Post subject: Munich Show (Mineralientage) 2021 - New Discoveries (2) Shijiangshan |
|
|
The Shijiangshan Mines in Yinwu, Inner Mongolia Autonomous Region, China is becoming an inexhaustible source of 'best known'.
It started with the Borcarites with Cahnite (initially erroneously attributed to Huanggang), continued with the Olshanskyites, then the Roweites and recently the Imayoshiites. Well, we must add another species to the list of 'the best of' from this mine. In Munich they could seen fine specimens of the rare Tatarinovite associated with the cohort of other species of that mine, mine that will undoubtedly be a world reference in the near future.
To know more read the paper: Rare Borate Minerals from the Shijiangshan-Shalonggou Deposits, Hexigten Banner, Inner Mongolia, China at the Rocks & Minerals magazine (Volume 96, 2021 - Issue 5 - Pages 392-409, authors Dr. César Menor-Salván, Berthold Ottens and Ed Richards

Official news is that next year's show will be held on the weekend straddling September and October, which overlaps with Oktoberfest, the world's largest beer festival.
When attending a small mineral show this morning in Paris, I was told by several dealers who also exhibit in Munich that the organizers of the largest European show are actually looking for an alternate date, possibly on early December 2022.

It doesn't seem to me a very good idea, the winter weather in Munich could be complicated, especially moving by car, and many people have already booked flights and hotels for the official dates...

11 months before the official date (overlapped with Oktoberfest) my hotel room price had already been multiplied by 2.5. I guess as that date approaches it might be multiplied by 4. And the flight tickets will be unavailable. I much prefer to be cold than not make the trip.

When the Mineralientage overlapped with the Oktoberfest in the past (two times) the people did reservation in cities around Munich at 100 km far or so, but well connected by train with the Messe.
One hour more every day and the extra charge for the train's tickets but cheap prices for the hotels.

Might be a solution, but it adds more stress and pressure to the trip just to save not much money: the flight tickets will be expensive and difficult to get anyway, and the hotel owners in Munich surroundings are not stupid.

I continue with the (scarce) news that I saw in Munich 2021. After two years it is difficult to say what was new in Munich or what was stored and was previously appearing on web pages or in small Shows prior to Munich, but I can say that these three things found during the pandemic period stood out in Munich.
- A relatively large geode that was found in the Bou Nahas Mine in July 2020 and that gave more than 50 pieces of idiomorphic Baryte crystals, some very large, almost completely coated by small Pyrite crystals that form a kind of mosaic, giving very aesthetic specimens with a lot of color and luster.
- After exhaustive analyzes made at the Muséum National d'Histoire Naturelle in Paris, some curious green crystals found in Kakanda, R.D. Congo, turned out to be Kolwezite after Cuprite crystals. As them sometimes appear on druses of cobaltoan Calcite with a very intense color, the whole combo is very pleasant.
- Shortly before the start of the pandemic, in Trepča were found good crystals of Bournonite on the typical sulfide combos from there, and during the pandemic period they have continued to emerge, even better than the first ones, brighter and with more defined crystal faces, and therefore with a quality that makes them compete well with those of other famous localities.
More reviews coming soon...

As we said yesterday ... 😉
Due to some slight vision problems I have not been able to close my chronicle so far, and, curiously, things have happened along the way.
Those 'Tatarinovitas' came with the analysis of a prestigious German University, but despite the fact that Dr. César Menor-Salván has analyzed each and every sample to exhaustion with the help even of N.V. Chukanov, one of the discoverers of the species, has not been able to find Tatarinovite there. The fact is that Imayoshiite and Tatarinovite are two extremely similar species and, of course, there is no doubt that Tatarinovite is in the Shijiangshan Mine, but in the specimens of the photos of Munich Show (Mineralientage) 2021 - New Discoveries (2) Shijiangshan there are Imayoshiite, Datolite (variety bakerite), Bultfonteinite, Axinite- (Fe), Andradite and Schorl but not Tatarinovite.
One more proof of how important the analytical results are today, especially when compared to earlier times when minerals were 'named' quite easily.
I close my chronicle of Munich 2021 with images of another of the few novelties of that edition, some beautiful Golds from La Rinconada, Ananea District, Puno Department, Peru.
