Résumé

Structures formed during indentation and lateral escape in Ishtar Terra on Venus (a planet without plate tectonics) form part of a regional shear system interpreted from Bouguer gravity and resemble the Himalayas or Eastern Alps on Earth. The large displacements of areas of continent-like crust are interpreted to result from mantle tractions / pressure acting against their deep lithospheric mantle 'keels' commensurate with mantle plume-related extension in adjacent rifts. This new perspective of Venus provides an analogue for an Archean Earth without plate tectonics.
