Photomicrographs of thin sections of representative marbles from C23 (a, b, c, d) and C24 (e, f, g, h) observed in crossed polarized light. (a) calcitic marble from the centre of the theatre hill; (b) dolomitic marble from the western extremity of the main lens of the quarry; (c) calcitic marble sampled in the Inopos reservoir folding, in contact with amphibolite, showing a succession of calcite, quartz and pyroxene veins; (d) calcitic marble from the highly thinned part of the lens, eastern part of theatre hill, showing calcite cleavage folding; (e) calcitic marble from the northern lens of Ghlastropi hill quarry; (f) dolomitic marble from the northern lens of Ghlastropi hill quarry; (g) calcitic marble sampled in the core of the tight C24 fold, showing a large humite with fluorphlogopite and clinochlore; (h) calcitic marble from the southwestern part of the main Ghlastropi lens, showing a centimetre-size calcite crystal.
