Economical geology of Belence (Eğirdir - İsparta) black marble deposits

ABSTRACT : Belence Black Marble deposits occur in Paleozoic metamorphic series. The metamorphic series consist of schist, quartzitc, calcschist, metasandstone, metaconglomerate, slate and recristalized limestone (black, marble),. Black marbles present in. two different .areas as Katırtaşı and Hacı Ilyas, Belence vicinity. The Black .marbles are thick-middle bedded and locally massive. Marbles are cut white calsite veins and. veinlets (0.3 mm- 3 cm thick). The black marbles are homogeneous in colour and texture laterally and vertically., Under microskopy, at thin sections of marbles, fine grained (10 - 75 micron) calsite .and microsparitic texture have been observed. The black marbles contain, calcite, quartz and opaque minerals.. Technological experiments showed that marbles can be cut as plate and marble tile (0-9 cm. thick.) and polished well. Phiysico-mechanicai tests have been, done on the Belence marble and their results, have been found as right TS 2513 and TS 1910. Reserve of Belence Black Marble deposite are, as indicated, reserve, total 209 375 000 m.3 (Katırtaşı; 75 000 000 m3 + Hacı Ilyas; 134 37.5 000)
