Abstract
Several types of decorative stones, mostly consisting of Mesozoic carbonates and mafic-ultramafic ophiolitic lithologies, crop out in Albania. They are in physical continuity with thè marbles of Greece and Turkey, which have been intensively quarried since ancient times. These rocks are in particular demand by thè stone material market, and have good physical-mechanical characteristics. The potential stone districts in Albania are here identified and described from both thè petrographic and physical-mechanical point of view. The most important marbles are: thè Early Permian-Triassic gypsum and alabaster; Middle Triassic limestones and dolomites; Early-Middle Liassic grey limestones; Late Liassic red ammonitic limestones; Dogger-Malm pink-brown limestones; Late Cretaceous pelagic limestones (pink and red in colour); Early-Middle Eocenic grey limestones, and Messinian gypsum and alabaster. The most important granites are thè Carboniferous-Permian leucogranites of Trokuzi and Fierza and thè intrusive ophiolitic rocks (whose composition range from mafic-ultramafic to acidic). Dunites (green marbles) are rare and scarcely productive.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
