Erdőbényei opál lelőhely

Geology: The dirt road leading to the pastures in front of the entrance to the Aranyos Valley first reveals hydrocartzite and later (about 200-300 meters) opal winters, which were formed partly in Miocene andesite and partly in colored banded rhyolite. Description: Going from Erdőbénye in the direction of Ligetmajor, in the bend in front of the Ligetmajor forest, the dirt road leading to Mogyorós opens to the right, at the beginning of which large, colored hydroquartzite blocks can be found, with deposited opal debris. After a bend in the road, the road splits in two and then reunites - in this area there are white, yellow, orange, brown and red opals of extremely beautiful, varied appearance and magnitude, sometimes even in dm blocks. Particularly beautiful are the stained, mottled and black manganese oxides. dendritic specimens. The excavation is free to walk around, after heavy rains the supply is very rich.
