Geology of the Imdr Regio area of Venus

We present a 1:5,000,000 geological map of the Imdr Regio area of Venus. Geological mapping was conducted using synthetic aperture radar (SAR) images, altimetry and stereo-derived topography data from NASA's Magellan mission. The map covers an area of approximately 7.9 × 106 km2 and exhibits a...

Descrição
Resumo:We present a 1:5,000,000 geological map of the Imdr Regio area of Venus. Geological mapping was conducted using synthetic aperture radar (SAR) images, altimetry and stereo-derived topography data from NASA's Magellan mission. The map covers an area of approximately 7.9 × 106 km2 and exhibits a variety of tectonic structures and units of volcanic origin related to the evolution of Imdr Regio and surrounding plains. We have differentiated primary structures related to the emplacement of the different units from tectonic structures that deform them. These structures are also organized between those that are regional in extent and those that are related to the evolution of local large tectono-volcanic structures. The units in the map area represent different geologic processes (e.g. volcanism) that took place during the evolution of the large topographic rise. Geologic mapping illustrates a complex evolution with different styles of deformation and volcanism in this part of the planet.
