This rocks, in base of mechanical-physics determination, are definite like "heavy, thinly absorbing, with strong resistance in dry condition and vicious weather immunity" rocks. Because of this are adequate to be used in the following ways:
like raw material in glass industry and fi ne ceramics, class I and II of quality;
At this using are capable, without exceptions, all accumulations of crystalline tames and crystalline limestone from territory, and it is estimate that in the future will have the same used.
The geological and technological potential of resource is superior to present's requirements and can cower the substantial growing of demands. We need to know that they have big extension in massifs Preluca, Borcut, Inau and Rodna, where can be contoured new perimeters with not so many works of geological research.
