Hi all,
I begin today uploading some pics of the exhibition "MKA, 50 years young" of which Jordi spoke in the previous post. It displays belgian minerals and minerals of the former belgian colonies: Rwanda, Burundi and D.R. of Congo (especially the latter one).
The exhibition is composed of samples (collected personally in many cases) belonging to the following members of MKA: Raymond Dedeyne, Rik Dillen, Jef Leybaert, Cyriel Matthé, Ludo Van Goethem, Paul Van hee, Albert Vercammen, Renaud Vochten and Iván Blanco. The exhibition includes some historical specimens of the Koninklijk Belgisch Instituut voor Natuurwetenschappen Brussels, and the Musée National d'Histoire Naturelle du Luxembourg, whom we do thank for their cooperation.
As an "aperitif", here is an overview of the 17 display cases.

Hi, here some pics of the first display case. Sorry for the quality of some photos.
To have an idea of the specimen's dimension, please consider that the labels are 64 mm wide (~2.5 inches).
Enjoy it!

Smithsonite
La Calamine, Moresnet, Kelmis, Liège Province, Belgium
22 x 12 cm aprox.
One of the best known specimens of smithsonite (if not the best) from "La Calamine".
The mine was abandoned and flooded in 1884, so all the pieces in the collections are from the nineteenth century.
This one was in the collection of Henri Buttgenbach, Professor of Mineralogy, Crystallography and Petrology of the University of Liege in the first quarter of the twentieth century. |

Hi,
the display case No. 4 is dedicated to the quarry located near Mont-sur-Marchienne, which has produced calcites with a great variety of crystal habits and combinations of forms. Twinned calcites are one of the identity signs of this quarry, which is already history.
| Description: |
| The number 42 (November-December 2002) of the journal "Le Règne Minéral" devotes a full article to this quarry. The specimen of the cover is shown in this case. |

Hi,
Let’s continue travelling across the world of Belgian calcites with the display case N°6, where representative specimens from Leffe, Rhisnes, Bioul, Chokier, Namèche, Couillet (Solvay), Landelies, Resteigne and Loverval are shown. Again some of them were collected in the decades of the 60's and 70's of the past century, even in the 19th century.

Today we conclude this "fast tour" through Belgium with the showcase 9. Then we will continue with the former Belgian colonies: D.R.Congo, Rwanda and Burundi.
The display case N ° 9 is basically dedicated to the porphyry quarry of Quenast, one of the largest quarries in Europe. Quenast has been and continues to be –together with other nearby quarries such as Bierghes- the primary source of porphyry rocks for construction in Belgium and the north of France.
The porphyry rocks in this area of the Silurian period (about 435 million years ago), formed during the Caledonian orogeny, in a subvolcanic environment associated with a subduction zone (Gondwana subducted under Avalonia).

Gold dust
The glass tube is about 9 cm long, containing 0.2 g.
This gold dust was in the collection of Jean Soudan (BE), which was sent with the army to the Belgian Congo in 1960 to maintain order after the declaration of independence. The curiosity is that this gold powder was exchanged to the local people by cigarettes. |
