It has been suggested by Schatzman (1977) that the empirical lithium content/age relationship found by Herbig (1965) could be explained by exchange of matter between the convective zone and deeper layers, where the rate of lithium burning is higher, by turbulent diffusion. The claim by Tassoul and Tassoul (1983) that such a turbulence is necessary to obtain a self-consistent description of stellar rotation and meridional circulation has given some momentum to Schatzman's proposal, as well as other successes of the turbulent diffusion hypothesis (Schatzman et al. 1981).
