Myers et al. - Two material analogue experiments of lava dome extrusion

Here we provide the full dataset to accompany the experiments presented in Myers et al. (2024) Lava dome morphology controlled by viscosity and cohesion: analogue experiments of episodic dome growth. We systematically explored the effect of cohesion and viscosity by carrying out experiments using (1) only granular material (sand, sand with 10 wt.% gypsum, and sand with 20 wt.% gypsum); (2) each granular material with a low viscosity syrup-sugar suspension, with 30 wt.% sugar; and (3) each granular material with a high viscosity syrup-sugar suspension, with 50 wt.% sugar.
