Abstract
In anticipation of MAGELLAN data on the Venera 8 and Venera 13 geologic-tectonic settings, I have restudied the possible terrestrial chemical counterparts of the materials at these landing sites on the basis of the most recent terrestrial geochemical data. My results indicate that the primitive mafic composition of the Venera 13 material is quite dissimilar to the inferred evolved intermediate composition of the Venera 8 material, suggesting the existence of continental crust on Venus.
