Foto: Hoslovice - historical quarrying of syenite porphyry
Hoslovice - historická těžba syenitového porfyru,
The exposure of the syenite porphyry is situated in a forest on the northern slope of the Chrasnice hill (elevation 711 m), 1.5 km south-east. from the village Hoslovice. About 200 m from the site passes a yellow marked hiking trail, which leads from the south from the village Hořejšice to the north to Hoslovice. The wider surroundings are being built by stromatitic biotite migmatite, and in addition to the porphyry veins, small penetrations of biotite granite are approaching.The massive and bizarre rock suggesting a mushroom is up to 5 m high, partly broken up into blocks of 1–5 m in size and forms a small rock town. Porphyry was used, for example, on millstones, which have been preserved in a nearby Hoslov water mill, which is recently a museum. Flat exfoliation is noticeable, according to which the porphyry breaks into thinner decimeter plates. | Žáček, Vladimír | 2016
