Abstract
The study considers the hydrothermal alteration of the volcanic rocks in the Köprülü region (western Turkey). Four alteration zones related to hydrothermal solutions have been determined: unaltered/fresh (UZ), altered (AZ), ferrous (FZ) and ferrous and manganese (FMZ). The distribution of the zones is closely related to the fracture/fault pattern. In addition to microscopic examination and X-ray diffraction, the physico-mechanical properties of the samples were established. A positive correlation was found between the mineralogical alteration index, water absorption and apparent porosity. However, there is an inverse relationship between uniaxial compressive strength and mineralogical alteration index (MI). The good correlation (r 2 = 0.822) between MI and strength ratio (Rs) indicates that MI can be a useful tool in determining the alteration degree of volcanic rocks, which has an important effect on their use in the construction industry.
Résumé
L’étude concerne les altérations hydrothermales des roches volcaniques dans la région de Köprülü (ouest de la Turquie). Quatre zones d’altération ont été déterminées: inaltérée (UZ), altérée (AZ), ferreuse (FZ) et ferreuse avec manganèse (FMZ). La distribution des zones est étroitement concordance avec le modèle de la fracture/faille. En plus de l’examen microscopique, la diffractométrie des rayons X et les propriétés physico-mécaniques ont été étudiées. Une corrélation positive a été établie entre l’index d’altération minéralogique l’absorption d’eau et la porosité apparente. Une proportionnalité inverse a toutefois été observée entre la force de compression uniaxiale et l’index d’altération minéralogique (MI). La bonne corrélation (r 2 = 0.822) notée entre MI et le coefficient de force (RS) indique que le MI peut être une méthode efficace pour la détermination du degré d’altération des roches volcaniques, ce qui a un effet important sur leur usage dans l’industrie de la construction.
