Reassessing the thermal structure of oceanic lithosphere with revised global inventories of basement depths and heat flow measurements

FD Richards, MJ Hoggard, LR Cowton… - Journal of Geophysical …, 2018‏ - Wiley Online Library
Half‐space cooling and plate models of varying complexity have been proposed to account
for changes in basement depth and heat flow as a function of lithospheric age in the oceanic …

Continental residual topography extracted from global analysis of crustal structure

SN Stephenson, MJ Hoggard… - … Research: Solid Earth, 2024‏ - Wiley Online Library
Continental topography is dominantly controlled by a combination of crustal thickness and
