- •
Gravity and magnetic data collected over Lake Purrumbete Maar involved unique methods to conduct the surveys over a lake.
- •
Geophysical interpretation and modelling suggests Lake Purrumbete Maar consists of multiple shallow coalesced vents.
- •
Potential field inversion results suggest the diatreme depth inferred by excavated accidental lithics is an underestimate.
