Be Care : this entry is the same as "Roua Mines, Gorges de Daluis, Guillaumes, Alpes Maritimes, France". You can see this one for more informations.

Does this need to be merged? (I am not familiar with this area, but have heard of the Roua mine.)

Peter Haas already commented on this problem in the Managers' Forum:

"There is at least an inconsistency in that the local language name doesn't display the same hierarchy levels, i.e. "Puget-ThÃ©niers" vs. "Guillaumes"."

Bonjour Ã tous,

C'est le secteur du DÃ´me de Barrot. Il y a ces deux liens :

http://www.pays-de-guillaumes.com/frameset/index.htm

http://asnatnic.club.fr/secgeo.htm

Il y a aussi un livre non citÃ©, je crois : Les anciennes mines de cuivre du DÃ´me de Barrot (Alpes Maritimes) par G. Mari, Ã©ditions Serre, 1992

Ce secteur du DÃ´me de Barrot comprend :

- Les indices de la Clue de Roua (une quinzaine de petites galeries) qui semblent Ãªtre appelÃ©s "mines de Roua")

- GÃ®te du Pont des Roberts

- L'indice de Tireboeuf

- Le gÃ®te de Bancairon

- Indice de la faille de CantÃ©

- Indices du vallon de BerthÃ©ou

- Le gÃ®te de l'Hubac de Jourdan avec plusieurs indices

- GÃ®te de LÃ©ouvÃ©

- Indices du Raton

- Indices de Liouc, de la Cime de Serraye, du Col de Roua, de la TÃªte de Giordanet, de la CrÃªte de FornÃ©

- GÃ®te de Villaron-La NouguiÃ¨re

- GÃ®te du Cerisier

Bien amicalement.

Yes.

Bonsoir Ã tous,

effectivement la clue de roua et les mines de roua ne sont qu'un seul et mÃªme endroit, par chez nous on parle des "mines de roua" pour dÃ©signer l'ensemble des mines, et la "clue de roua" est un torrent Ã proximitÃ© immÃ©diate du groupe de galeries nord bien connu des amateurs de rafting du coin, par contre les descriptions ne sont pas identiques.

Serge ta liste n'est pas mal mais il me semble que LÃ©ouvÃ©, Le Cerisier, Villaron et Raton ne sont pas dans la zone de Roua, mais plutÃ´t de Puget Thenier (autre bassin versant).

Par contre il est vrai qu'il manque de la doc, notamment quelques articles dans riviera scientifique, ou plus simplement "Mines et MinÃ©raux des A.M." par G.Mari !

Il est Ã noter que les mines (si si avec des galeries) de l'Hubac de Jourdan et de BancaÃ¯ron ont Ã©tÃ© "sÃ©curisÃ©es" Ã l'aide de ... dynamite, peut Ãªtre pour Ã©viter qu'un loup ne s'y casse une dent !...

AmitiÃ©s

Fixed (finally!).

A noter que dans "l'inventaire mineralogique de la france tome 6 - alpes maritimes (1973)" l'indice est decrit sous le nom de "clue de rocca" et non Roua.

Yes, when we were preparing the mineralogical inventory of the whole district in 1966 (eventually published in 1972), we found in the Archives of the District of Nice, me and my friend Paul Duvochel, an old, official, handwritten report dating from 1864, signed by the engineer of mines who was in charge of the mining licenses of the area. This engineer, Victor Juge, a recknowned scientist for the area in that time, reported of the discovery of this (very small) mine. He was naming the mine Clue de (it was difficult to read the handwritten word) Rocca, or Roua. The two legs of the U letter of the word were curved and we had the choice: Rocca in the local language means ROCK (and this gorge is much rocky!) and Roua is a very small village nearby. We selected ROCCA. It proved to be wrong.

Sorry!

I am glad to grasp this opportunity to reset a truth: the true inventor of this mineralogical occurrence was not Gilbert Mari in the 90's (and not me in the 70's) but Jean VERNET, whose grandgrandfather was this engineer Victor Juge. Jean Vernet was a great climber as well as a geologist full of energy and HE re-discovered all these small galleries in 1952-1955.

Later on, the link was done by him and a few other scientists in BRGM (among whom the famous Paul PICOT in BRGM and Paul SAINFELD in the mineralogical gallery of Paris school of Mines) that the old samples of native copper exhibited in this museum and being 15 to 25 cm x10 cm in size) came from these mines as well (they were a gift from Victor Juge).

These specimen were then cut in polished sections whilst Vernet gathered new specimen from the mines. Alltogether were then identified the algodonite, domeykite, koutekite, silver, gold and electrum in this deposit, making it a very original mineralogical locality for France, already. It was in 1965 !!

It is a pity that these early discoverers are generally forgotten by the new authors, who really deserve to be proud to have discovered the new arseniates, but they forget too quickly that the very original sulphides of the deposit (despite not NEW species) were discovered by these scientists 25 years before them.

Regards

Jean Feraud (BRGM)
