Numerous volcanic centers on Venus include among others shield volcanoes and coronae. The volcanoes are characterized by their dome/cone-shaped topography and a radial pattern of lava flows while the coronae manifest itself by tectonized annular rim and many of them lack distinct volcanic features. While the models of the formation of volcanoes and coronae are abundant, only a few papers consider the relative ages of the volcanoes and coronae. However, their stratigraphic relationships likely represent a crucial component of our understanding of the thermal evolution of Venus. In this work we present preliminary results suggesting the change of the style of central volcanism on Venus through time.
