Περίληψη

Quarrying activity concerning "Petra Thymianon" (= Thymianα Stone) is located in the homonymous region of Chios Island. This structural stone is experientially classified into four commercial types, bearing the quarrymen jargon names: "Hemsk-liri" (= Medium Hard), "Triandafylli" (= Rose Pink), "Malaki" (= Soft), "Melidjani"(= Purple). All those types consist mainly of carbonates. In a lesser extent, quartz, leafshaped minerals, and iron oxides - hydroxides occur. Geologically, Thymianα Stone is characterized as "Carbonaceous - Ferruginous Pelite". It is a sedimentary thinbedded rock with alternating layers of calcareous pelite and ultra fine-grained sandstone. Very low grade metamorphism is also present. The quarry production consists of blocks, being cut to slabs for paving and flooring and to shaped stone units for masonry. In this study, the physical mechanical properties of the various Thymianα Stone types have been determined according to the relevant EN Standards. Furthermore, the physical meaning of the quarrymen jargon has been established in connection with the stone types' quality characteristics and potential applications.
