48° 11′ 15” N lat.; 22° 46′ 48″ E long.

Square 0,3 hectares. Cliff

Mineralogical, geomorphologic.

On the right bank of Borzhava River there rises up a medium hill with castle ruins which comprises erosion remnant composed of erosion-resistant secondary quartzites. The latter were formed by hydrothermal-metasomatic alteration after Lower Sarmatian rhyolite tuffs. There is range of cliffs up to 5 m height.

Quartzites contain silver-barite-polymetallic mineralization and comprise ore-bearing rocks of the Kvasivskiy silver prospect. It is resulted from hydrothermal activity of deep-seated ore-forming fluids at post-volcanic stage of Neogene tectonic-magmatic activization.

Ecological conditions are suitable; cliffs are overgrown with shrubs.

Accessible by motor-car.
