Na Skalách (1037m) is a subpeak in the Klínovec massif (Keilberg, 1244 m), which consists of an eclogite body in orthogneisses. Eclogite was changed by retrograde metamorphism, hence it contains younger coarse-grained bands of quartz, amphibole and zoisite. In this bands occur frequent crystals and grains of rutile, commonly up to 15 mm, the biggest up to 40 mm. Nice are also blue-green ruler-shaped crystals of amphibole and tanish prismatic crystals of zoisite. Unusual is occurrence of fluorapatite, which forms tabular crystals in sugar-like quartz. Zoisite and fluorapatite were confirmed by X-ray analysis.
