Remnants of an extensive maar-diatreme volcanic field are magnificently. Rich in sandy mudrock derived from the pre-eruptive Mio-Pliocene Bidahochi Formation. Busby-Spera CJ, White JDL (1987) Variation in peperite textures associated. They compared it to a similar butte formation in the Czech Republic. Their hypothesis suggests that the Tower is the result of a maar-diatreme volcano (Figure 4). These form when magma encounters groundwater beneath the Earth’s surface. The super-heated water becomes steam. This steam expands explosively creating a crater on the surface.
