A shear heating origin for ridges on Triton

  title={A shear heating origin for ridges on Triton},
  author={Louise M. Prockter and Francis Nimmo and Robert T. Pappalardo},
[1] Triton and Europa each display a variety of distinctive curvilinear ridges and associated troughs. Here we propose that ridges on Triton may have formed by diurnal tidal stresses, in a manner similar to that proposed for ridge formation on Europa. The greater width of ridges on Triton is likely a consequence of the lower surface temperature and greater brittle-ductile transition depth on this body compared to Europa. The magnitudes of the stresses and heat fluxes required to generate ridges… CONTINUE READING
