 On and under the course of the sliding, there are a whole series of smaller and larger deposits of siderite and limonite.Those are among the ones in Steinbachgraben and Rohrerwald near Turrach, which were the basis for the iron smelting there.The most commonly appearing minerals on the Turracher Höhe are the "Gurktal phyllite" (created in the Lower Silurian) and "Eisenhutschiefer" (Upper Silurian to Middle Devonian), and on the other side of the Gurktal layer also Altkristallin (paragneiss, mica schist, amphibolite), some of which were created in the Ediacaran Period.
