Spannagel Cave do not support the formation of caves. The only exceptions are pockets of rock capable of karstification such as limestone, dolomite, gypsum and other carbonates.

The Spannagel Cave has arisen in a large vein of Jurassic calcite marble of the Hochstegen Formation, a marble with over 90% total carbonate content, that runs through the slate mantle of the "Western Tauern window". The formation of this extensive cave as a result of geological corrosion (and mixing corrosion)
