Examples of the median Markov-chain Monte-Carlo model fits to olivine centrifuge experiments. The fits generated here treat \(\xi_{\text{ref}}\) and \(\phi_{m}\) as material parameters. These parameters are tabulated in table 3 and presented visually in Fig. 10 . A) ZOB9, B) ZOB6, C) ZOB1, D) ZOB11, E) ZOB5, F) ZOB10, and G) ZOB4. H) Contributions of shear and bulk viscous components in eq. (16) using \(\xi_{\text{ref}}\) and \(\phi_{m}\)inferred from applying numerical model to the porosity profiles in panels A through G.
