Solidification dynamics in channeled viscoplastic lava flows

Robertson, Jesse; Kerr, Ross


[1] The influence of a viscoplastic lava rheology on the dynamics of channeled lava flows is analyzed using analogue experiments. The experiments used slurries of polyethylene glycol and kaolin, which flowed with a constant flux down an inclined channel under water. Three sets of complementary experiments are presented: isothermal, cooling, and solidifying flows which quantified the effects of the viscoplastic rheology on shear, internal convection and surface crust formation. The isothermal...[Show more]
