Extended Data Fig. 4: Partial melt generated by lithospheric thinning.
From: Preferential localized thinning of lithospheric mantle in the melt-poor Malawi Rift
Integrated partial melt is displayed as total kilometres of igneous material added to the crust. Dependence on asthenospheric potential temperature and crustal beta factor are shown. In this calculation, lithospheric mantle thinning is assumed to be twice the magnitude of crustal thinning, based on our observations of present-day thinning across the Malawi Rift. Accardo et al. 14 estimate uppermost mantle temperatures most consistent with the cooler end of the range of potential temperatures shown here.
