1 G\u00e9ographie \/ G\u00e9ologie<\/h2>

\u00a0<\/strong>La S.A. Calcaire de Vinalmont exploite \u00e0 Vinalmont une pierre bleue dite et commercialis\u00e9e sous l'appellation \"PIERRE CALCAIRE DE MEUSE - PIERRE DE VINALMONT\". La carri\u00e8re est situ\u00e9e \u00e0 Vinalmont, dans la vall\u00e9e d\u00e9nomm\u00e9e Fonds du Roua, \u00e0 l'ouest du centre de Vinalmont, dans le flanc nord du Synclinorium de Namur. Coordonn\u00e9es Lambert: N 50\u00b0 34' 6'' E 5\u00b0 12' 10''.<\/p>

Le mat\u00e9riau est utilis\u00e9 comme pierre de construction et roche ornementale. Dans la carri\u00e8re on exploite une roche calcaire, compact \u00e0 grain fin, non poreuse, de teinte gris clair \u00e0 gris-beige en face sci\u00e9e et de teinte gris fonc\u00e9 en cassure fraiche. La pierre prend une patine gris clair sp\u00e9cifique \u00e0 ce mat\u00e9riau. Les couches exploit\u00e9es se situent en bordure nord du Bassin de Namur, \u00e0 l'est de la M\u00e9haigne, et constituent la Formation de Neffe d'\u00e2ge Moliniacien sup\u00e9rieur, s\u00e9rie vis\u00e9enne (V2a)-Mississippien, Carbonif\u00e8re inf\u00e9rieur.<\/p>

La roche est massive et d\u00e9coup\u00e9e par trois r\u00e9seaux de diaclases, presque perpendiculairement aux lits. L'exploitation se fait \u00e0 ciel ouvert; les bancs ont une direction d'environ N72\u00b0-81\u00b0E et une inclinaison de 5\u00b0 -10\u00b0S.<\/p>

La puissance totale d'un seul tenant est d'environ 38 m. L'agr\u00e9ment concerne les parties de qualit\u00e9 comparable de la carri\u00e8re, c'est-\u00e0- dire l'ensemble du banc homog\u00e8ne massif de 30 m d'\u00e9paisseur de couleur gris clair qui sont clairement identifi\u00e9s sur la coupe (cf. p. 5 annexe 1, coupe g\u00e9ologique), contenant peu de stylolithes. Ces stylolithes fortement indent\u00e9s (forme d'\u00e9lectrocardiogramme) sont particuliers \u00e0 la pierre de Vinalmont. Lorsqu'ils sont ferm\u00e9s, soud\u00e9s, ils permettent le d\u00e9bitage des blocs \u00e0 contre-passe ou \u00e0 passe.<\/p>

Les lim\u00e9s, lorsqu'ils sont mal soud\u00e9s et tr\u00e8s fins (inf\u00e9rieurs \u00e0 0,1 mm) sont \u00e0 exclure car ils constituent des endroits pr\u00e9f\u00e9rentiels de rupture de la roche. Ceux-ci casseront g\u00e9n\u00e9ralement lors de la transformation de la roche.<\/p>

2 P\u00e9trography \/ Lithology<\/h2>

\u00a0<\/strong>Description macroscopique:<\/u> \"PIERRE CALCAIRE DE MEUSE - PIERRE DE VINALMONT\" est un calcaire oolithique compact, d'origine s\u00e9dimentaire d'une tr\u00e8s grande puret\u00e9 chimique, \u00e0 texture homog\u00e8ne pr\u00e9sentant une stratification entrecrois\u00e9e, mise en \u00e9vidence par la patine. La teinte est gris clair \u00e0 gris-beige en face sci\u00e9e et gris fonc\u00e9 en cassure fraiche. La pierre prend une patine gris clair sp\u00e9cifique \u00e0 ce mat\u00e9riau. La patine, due au vieillissement et inh\u00e9rente \u00e0 la composition de la pierre, doit \u00eatre prise en compte dans le cadre de restaurations. Le calcaire contient des fragments de coraux (certains bancs sont riches en coraux du genre Siphonodendron) et des coquilles de brachiopodes et de gast\u00e9ropodes.<\/p>

Selon le PTV 819-4 'Classifications des roches dans le cadre de l'homologation en r\u00e9f\u00e9rence \u00e0 la NBN EN 12670', il s'agit d'une roche s\u00e9dimentaire carbonat\u00e9e - calcaire o\u00f6lithique: 2.2.1.3.<\/p>

Description microscopique<\/u>: \"PIERRE CALCAIRE DE MEUSE - PIERRE DE VINALMONT\" est un calcaire oolithique bioclastique riche en pellets. La roche est principalement compos\u00e9e de microfossiles abondants, dont des foraminif\u00e8res diagnostiques de l'\u00e2ge et pr\u00e9sentant une texture packstone \u00e0 grainstone (classification DUNHAM) ou d'une biosparite \u00e0 une biomicrite (classification FOLK, cf. NBN EN 12670). D'autres particularit\u00e9s lithologiques peuvent \u00eatre pr\u00e9sentes.<\/p>

Composition (\u00e0 titre informatif).<\/u>: La composition moyenne est de 99 % de carbonate de calcium (CaCO3) en absolu, de 0,5% to 1% de silice (SiO2), d'oxydes de fer, de mangan\u00e8se et de magn\u00e9sium.<\/p>
