Shale oil
It is also known as Ichthyol. According to legend, it is the blood of the giant Thyrsus; hence, it is also called "Thyrsenblut" or "Dirschenblut". From the "Thyrsenblut" the healing Tyrolean shale oil is extracted. Shale oil reserves are located in the oil shale at Seefeld in Bächen Valley plate and close to Achen Lake. The oil-bearing zones lie at an angle of 51 degrees.
