The TRACK project is intended to complement the Eifel-plume project and will connect the former with the existing Auvergne (Massif Central plume) network, allowing investigation of sub-lithospheric mantle structure as far south as the Golf of Lion. TRACK will look for the missing head of the Massif Central plume as well as for any possible connections with the Eifel region, making use of seismic tomography and anisotropy studies. TRACK is scheduled for summer 1998 and involves the Universities of Strasbourg, Clermond-Ferrand, Montpellier, Leeds, Cambridge and the GFZ Potsdam.
