When geologists can’t look at rocks because they are several kilometers underground, they go look at similar rocks on surface. A type of rock (greywacke schist), similar to rocks deep under the Taupō Volcanic Zone in the central North Island, is exposed at Rarangi near Blenheim.
The team took numerous pictures using a standard camera. All these pictures were then combined to make this 3D view. The data will be used to measure the organization of fractures and veins at Rarangi then extrapolate to what could be deep under the Taupō Volcanic Zone.
