Geocache Description:

Tato keš se nachází u hradu Orlík nedaleko Humpolce.
This cache is located the castle Orlik near Humpolec.



 
Behem stredoveku je Orlík spojen s radou místních historických událostí. Zánik hradu se datuje zacátkem 18. století, behem 19. století sloužil objekt jako zdroj stavebního materiálu a byl témer rozebrán.
Pujdeme-li od hradu dále, mužeme asi po 400 metrech videt vpravo od lesní cesty cetné terénní nerovnosti  které jsou dokladem historické težby zlata v lokalite s místním názvem „Na Štulách“ nebo „Štuly“.
________________________________________
Zlatonosné zrudnení v okolí Orlíku bylo ve stredoveku teženo približne v paralelních pásmech , probíhajících v délce asi 600 m. Tyto rudní partie jsou uloženy v cordierit-biotitových migmatitech s výrazne polyschematickou stavbou tvorících soucást moldanubické oblasti. Po težbe se dochovaly rozsáhlé zbytky dobývek, šachtic a kutacích príkopu, na které v severovýchodní cásti navazuje pásmo depresí a haldicek. Tyto vznikly pri povrchovém rýžování zlata ze svahových uloženin.
Mocnost polohy zrudneného erlanu dosahovala 1,2 až 2,5 m se strmým úklonem k SSZ a je souhlasne uložena s foliací okolních hornin. Zlato vrustá do kremene nebo horninotvorných minerálu. Velikost zlatinek se pohybuje od nekolika mikrometru do 2-5 mm, u nejvetších z nich až do 10 mm. Zlato má vysokou ryzost a je doprovázeno dalšími rudními minerály…

The castle Orlík is associated during the Middle Ages with a number of local historical events. The loss of the castle is dated back to the beginning of the 18th century, during the 19th century building served as a source of building materials and has been almost dismantled.
If we go approx. 400 meters from the castle we can see the right side of the forest roads cross numerous inequalities that are the evidence of the historical gold mining in the region with the local name of "Na Stulách" or "Stuly".
________________________________________
In the Middle Ages the gold ore close to Orlik was extracted in quite parallel strips of the length about 600 m. These ore parts are stored in a batch-cordierite biotit migmatite with the significantly polyschematic building structure which builds a part of moldanubic area. After the extraction there were remains of an extensive ore mineralization, shafts and digs, where it is connected in the north-eastern part to the strip of natural depression ore slag heap. These arose during the surface gold-washing of the slope deposits.
Thickness of the mineralizating erlan position was from 1.2 up to 2.5 m with the sharp rake angle to the NNW and it is also saved with the surrounding rocks.The gold is growing in to the silica or rocky minerals. The nugget size ranges from several micrometers to 2-5 mm, the largest of them even up to 10 mm. Gold has a high purity and is associated with other ore minerals ...
