Plume separation at a viscosity boundary.
This page is very much under construction.
More details and info soon.
In this short movie is a model demonstration
of a low viscosity green plume encountering a clear vs. yellow
viscosity boundary and separating into two plumes. This is meant
to model double flood basalt production by a deep mantle plume
encountering the 670 km upper vs. lower mantle boundary. Demonstration
constructed and conducted by Troy Hays for a plate tectonics demonstration.
