Discontinuity Analysis at Ruschita Marble Quarry Using Televiewer and Scanline Techniques

Abstract Stone blocks, such as marble, granite, and sandstone, are natural materials with excellent properties. The most important dimension stone in Romania is Ruschita marble, a natural stone known for its resistance to wear and ability to maintain its natural beauty, regardless of its colour. Regarding colour palette, Ruschita marble stands out for its excellent quality to suit even the most demanding requirements. It is available in shades such as yellowish, orange, pale pink or pink, with a compact structure and characteristic veining. Ruschita is Romania’s most famous marble deposit, exploited since the end of the 19th century. The quarry exploitation is conditioned by naturally occurring fractures and discontinuities, such as faults, joints, and fissures, precluding larger blocks excavating with more significant commercial value. This paper describes two largely used techniques for discontinuity investigation, namely the televiewer and scanline methods used at the Ruschita marble quarry.
