Laboratory-Scale Simulation of Spiral Plumes in the Mantle
arXiv:1207.0717
Abstract
On the basis of laboratory simulation a mechanism is established for the formation of the upper mantle convection spiral plumes from a hot point in the presence of a roll-type large-scale convective flow. The observed plume has horizontal sections near the upper limit, which may lead to the formation of chains of volcanic islands.
