Greywacke Zone


The Schwarzphyllites originated from dark, clayey deposits in the deep sea. The dark, sometimes reddish color is due to oftenpresent organic components and iron compounds. However, none of the original clay minerals remain because the current mineral composition has formed through metamorphism (rock transformation) during a mountain-building process under extreme conditions (temperature ≈ 350°C - 550°C, pressure ≈ 200 - 1000 MPa).

Characteristic minerals now include mica, quartz, sometimes feldspar, chlorite, and iron oxide. The light layers were originally either sandy deposits or volcanic tuffs. The rocks are intensely schistose, often even multiple times, and folded. Despite the schistosity and metamorphism, the sedimentary structures are still recognizable.

The legend of the iron hen

The boisterous miners from the mines on the Iglsbach, at the eastern foot of the Hochgründeck, went to the beautiful daughter of the old Zechbauer woman, who was a sorceress. She did not want to leave her daughter to the miners and constantly rejected them with harsh words, even curses. But the squires were not deterred and continued to visit the beautiful Katharina. The old farmer's wife then decided to cast a spell on the entire miners' community.

So she decided to have an iron hen made with iron eggs and coated everything with boiling pitch and sulphur to prevent the iron from rusting. She then used magic spells to bury them in an unknown place. From that moment on, the rich ores at Iglsbach disappeared and the glory of the miners was over.

The miners then left the valley. Hardly anyone can still find old slag heaps and mining equipment along the Iglsbach today. Many years have passed since the old miner's wife died and the beautiful Katharina closed her eyes forever. But the magic still lies on the rich veins of ore at the foot of the Hochgründeck, which no one is able to find. This spell will not be lifted until either a Sunday child lifts the iron hen from the bosom of the earth, or the "magic work" is eaten away by rust and decays.
