From the geological viewpoint, the Turracher Höhe and its further surroundings belong to the Gurktal layer, whose Paleozoic rocks slid over the more recent rock layer of the so-called Stangalm Triassic Period. 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.
